The Inspector's Borrowed Seal

The Exchange Lock

The grown half was already waiting in the cradle when Marisol pulled herself into the exchange lock. It had not been there when she slept. Something had placed it while the outer door cycled, while the station turned its slow face away from the visitor craft and back again. It sat in the padded clamp like a stone pulled from a riverbed: palm-sized, pale, faintly ridged, with a hollow at its center shaped to receive something that did not yet exist.

Except it did exist. It was clipped to her chest harness in a soft case, and she could feel its weight through the fabric every time she moved.

"You're early," Kenji said from the inner hatch. He had a coffee bulb in one hand and the life-support tablet in the other, and he looked like he hadn't slept either. "They're early. Everybody's early."

"They put it out while the lock was dark." She anchored her boots in the floor loops and leaned close to the window of the transfer box without touching it. "No camera caught the arm. Nothing caught the arm."

"Maybe there wasn't an arm."

"There's always an arm."

He drifted in beside her, and the lock felt smaller with two people in it, which it always did and which she had stopped minding some months ago. His shoulder was warm against hers. He smelled of the scrubber room, that faint chalky bite of fresh absorbent.

The transfer box was her design, more or less. A cube with its own small atmosphere, matched to the lock on one side and to vacuum on the other, so that a thing could pass from them to us without either side ever opening to the other. She had certified every weld. She had signed the stamp across its frame herself, the old embossed inspector's mark that the consortium still required on anything a person might one day crawl through. Nobody would crawl through this. It was a box for hands and gloves and objects. But she had stamped it anyway, because she stamped everything, and because the habit steadied her.

"Pressure's matched," Kenji said, reading. "Their side's holding at whatever they hold at. Ours is ours. You're clear on my end."

"Thank you."

She unclipped the case and slid her half out. Titanium, machined in the station shop over the slow span of weeks while the visitors sent shapes and she sent shapes back, each of them learning by failure what the other could make. The faces had been the hard part. Their half was grown, not cut, and grown things don't come out where you tell them to. She'd had to read the ceramic's surface from scans, its tiny irregular terraces, and cut the titanium to meet it. There had been a version that almost fit. She had thrown that one in the recycler with her own hands and started again.

She slipped her gloves into the box sleeves. The cold reached her even through the liners.

"You want me to narrate?" Kenji asked.

"I want you to be quiet."

"Being quiet." He was smiling. She could hear it.

She lifted the grown half from its cradle. It was lighter than it looked, almost hollow-feeling, and the ridges along its rim were not quite symmetrical. She had known that from the scans. Knowing it from the scans was not the same as feeling it under her thumb. One ridge was thicker than its neighbors, a little shoulder of material, and she wondered whether it was a mistake or a signature or simply the way the thing had decided to grow.

She turned her own half to match. Turned it again. The titanium had a key, a notch, that should slide past that thick shoulder, and for a moment it didn't, and her heart did something stupid. Then she backed it off, breathed, came in at a shallower angle, and felt the notch find the shoulder like a foot finding a stair in the dark.

The two halves met.

It wasn't a click. Grown ceramic doesn't click against metal. It was a settling, a give that traveled up her fingers, and then a pressure, steady and even, as the seal's inner faces drew the two pieces together. The sensor strip she'd buried in the titanium lit along its edge. Contact all the way around.

"Oh," Kenji said.

"Don't."

"I didn't say anything."

"You said oh."

She held it. She didn't let go. That was the protocol she had written: hold it joined, count slowly in your head, watch the strip, let the pressure differential do its work across the seal's tiny test chamber. If there was a leak anywhere along the join, the strip would show it as a dimming arc, and the little chamber would lose what she'd given it. She watched the edge stay bright. She watched it stay bright for longer than she'd planned to watch it.

"Two seals," Kenji said softly. "One thing."

"Two halves."

"You always correct me when I'm being nice."

"You're being imprecise." But she looked over at him, finally, and he was close enough that she could see the tiredness under his eyes and the little scar at the corner of his mouth from a cracked visor, years before she knew him. He looked at the seal the way he looked at a scrubber bed coming back up to clean air. Like it was a living thing that had decided to keep going.

The strip held.

She separated the halves. That was the other part of the protocol, the part the consortium had argued about for a week. Each side would keep one. Not a gift, an exchange: a piece of us goes to them, a piece of them stays with us, and when either side wanted to speak in a way that mattered, the halves would come back here and be joined again. The board had wanted both halves. Marisol had said that a lock you hold both sides of is not a lock, it's a door you own. Somebody had written that down, and she wished they hadn't.

She set the titanium half into the cradle on the vacuum side. Withdrew the grown half to her side, into the lined tray, and let the box's inner panel close over it. Her gloves came out of the sleeves stiff with cold. She flexed them, and Kenji took her right hand without asking and rubbed the fingers between both of his.

"You're freezing."

"I'm fine."

"You're fine and freezing." He didn't let go. "Look."

The cradle on the far side was empty. Her half was gone. Again, no arm. Again, nothing on the cameras but a stutter in the frame and then absence.

"I'd like very much to know how they do that," she said.

"You could ask."

"With what?"

He nodded at the tray. "With that, I guess. Isn't that the point?"

It was the point. She knew it was the point. She lifted the grown half out of the tray and held it in her bare palm, which the protocol did not strictly forbid, and which she would have to write up anyway. It had warmed a little in the lock air. The thick ridge sat under her thumb. She traced it, the way she would trace a weld she was about to certify, feeling for porosity, for seams, for anything that would fail.

"You're inspecting it," Kenji said.

"I'm holding it."

"You're holding it like you're inspecting it."

"It's how I hold things." She meant it lightly. It didn't come out lightly. She closed her fingers over the ceramic and felt, beneath the surface, an unevenness she hadn't seen in the scans, a faint internal grain, as if it had been grown in layers she'd someday want to see. She filed the thought away carefully. Not today.

Outside the window, past the transfer box and the lock's outer skin, the visitor craft hung against the black. Its long flank caught the light from the planet below and gave nothing back. Out near its stern, where the drive housing would be if it were a ship like their ships, a faint haze clung to the hull, a bloom the station's instruments had been grumbling about since it arrived. Kenji's tablet chimed a small dosimetry note and he swiped it away without reading it.

"Achterberg'll want that number," Marisol said.

"Achterberg always wants a number." He squeezed her hand once and let it go. "Today, I want you to have the morning."

She looked down at the seal in her palm.

It pulsed.

Not a light, not a sound. A warmth, rising and falling once against her skin, soft as a held wrist, and then again, slower, as if something on the far side of the dark had taken her half into its own hands, felt the edge she'd cut, and answered.

Board Orders

Thandeka Rourke came into the inspection bay with the message still playing on her slate, the board chair's voice tinny and patient, already hours old by the time it reached Tessaly Station. She didn't wait for it to finish. She set the slate on the bench beside Marisol's calipers and let it run.

"...the consortium cannot accept an unsecured drive of unknown output parked within the station's operating envelope. Director Achterberg is authorized to board and render the drive safe. The board expects confirmation before the close of the current window. We'll review your reply when it arrives."

The recording ended. The chair's face froze mid-blink.

"When it arrives," Thandeka said. "They always say that like it's our fault the light is slow."

Marisol didn't look up. The grown half sat in its padded cradle under the bench lamp, pale and ridged, and the scanner arm hovered over it with its patient red line. Three nights of scans and she still couldn't resolve the inner grain she'd felt with her thumb. The images came back soft, as if the ceramic were politely declining to be seen.

"What's the close of the window?"

"Tomorrow." Thandeka pulled a stool over and sat on it the way she sat in every room, as though she'd been asked to and was doing everyone a favor. "Desmond's already prepping the Harrowind. He'll want your stamp tonight so the clamp crew can sleep."

"The clamp crew can sleep regardless."

"Marisol."

"I'm working."

The hatch cycled again and Desmond Achterberg ducked through it, still in the soft-shell jacket he wore on the cutter, a dosimeter badge clipped at his collar. He carried a printout, actual paper, which meant he'd wanted something he could put in her hand.

"Morning dose map," he said, and put it in her hand.

She looked at it because she had to. The haze off the visitor's stern was drawn in contour, a soft lobe reaching toward the station's ring and stopping short. The habitat side showed warm. Not dangerous yet. Warm in the way that made safety officers stop sleeping.

"It's been sitting there for days," she said. "It hasn't moved."

"It's been sitting there for days pointed at us." Desmond leaned on the bench, careful not to touch the cradle. She noticed that and liked him for it, which annoyed her. "I've got people living in that ring. Kenji pulls his shifts right under that lobe. I don't know what that drive is doing, and I can't ask it. The board's given me a way to stop guessing."

"By prying it open."

"By clamping on at the service hatch we mapped, cycling a temporary lock, and putting a team in to find the thing that's glowing. I've written it so nobody touches anything they don't have to." He tapped the paper. "I'm not a cowboy. You know that."

She did know it. That was the worst of it. He'd drilled the evacuation of the ring twice since the visitors arrived, and both times he'd been the last one through the bulkhead.

"They gave us a door," she said. "The exchange lock. They chose that. They made half a key and let me make the other half, and it fit, and they took mine. That's the entire vocabulary we have with them. You want to come in through a hatch they didn't offer."

"I want to come in through a hatch that won't kill my people."

Thandeka folded her hands. "Nobody's disputing the seal matters. I've sent the board everything you've written about it. They read it. They're scared anyway."

"They're scared from very far away."

"That's what boards are for."

Marisol set the dose map face down. Under the lamp, the grown half pulsed, faintly, the way it had every few hours since the first day. A warmth she could feel through the cradle padding if she rested her fingertips at its edge. She'd started timing her scans around it, waiting for it like a breath.

"I need to finish certifying the exchange lock before anything else happens near that ship," she said. "If they bring my half back, or if we have to join the halves again in a hurry, I have to know this one holds. I can't see the inner structure through the cradle. I'm pulling it."

Desmond frowned. "Pulling it where?"

"Out of the mount. Bare-bench. I'll run a contact scan, and if I have to, I'll take a surface scraping from the flange. A sliver. Nothing structural."

"You're going to cut their key," Thandeka said slowly.

"I'm going to inspect our key." Marisol was already gloving. "It's half ours. I signed for it."

She unlatched the cradle. The retaining fingers sprang back. She lifted the grown half out, and it was lighter than she remembered, or her hands were steadier than they'd been on the first day. She turned it under the lamp. The ridge. The flange where her titanium half had seated against it, and the faint polished arc where the two had pressed together.

She set it on the contact plate. The scanner head came down and touched it, and the bench screen filled with grain at last, fine layers stacked like the pages of a closed book. She heard herself make a small sound.

"There," she said. "There you are."

She took the micro-burr from her tool belt, chose the flange's outer lip where nothing seated, and drew it once across the surface. A curl of ceramic dust lifted and settled on the plate. She tipped it into a sample vial and capped it.

Then she waited for the pulse.

It should have come by now. She knew its rhythm better than her own. She laid two fingers on the ridge, bare skin through the glove's thin tip, and felt cool ceramic. Room temperature. Nothing rising, nothing falling.

"Marisol?" Thandeka had stood.

"Give it a moment."

Desmond was already on his wrist unit. "Ops, tell me what the visitor's doing."

The answer came back over his speaker, a watch officer's careful voice. "No change in position, Director. Haze is steady. But the low hum we've been logging off the hull, the one that matched the seal, it's gone. Dropped out a few minutes ago. Everything else is flat."

Marisol took her fingers off the ridge and put them back on, as if she'd missed it. Cool. Still.

"They felt that," she said. "They felt the burr."

"You don't know that." Desmond's voice had gentled, which was worse than if he'd shouted. "Could be anything. Could be they're powering up."

"It answered every time I held it. Every time. I took a piece off it and it stopped." She looked at the vial in her hand, the pale dust in it, and wanted badly to put it back. There was no putting it back. "I thought they'd see me checking it. Taking care of it. That's what I do with things I'm responsible for."

Thandeka said quietly, "Maybe that's not what it looked like from over there."

Nobody answered her. The bench lamp ticked as it cooled.

Desmond set his slate down beside the dose map. On it, the boarding authorization was already drafted, his signature in place, the board's in place, one empty field at the bottom with her certification number printed under it in grey.

"Then that's the end of talking," he said. "If they've gone quiet, I can't wait for them to explain. I need your stamp on the hatch survey. You certified that hull section. If I clamp without it, I'm clamping on a guess, and my team pays for the guess."

"If you clamp with it, they pay for mine."

"Marisol." Thandeka's voice was tired, and kind, and immovable. "The board will send the order again. And again. Eventually they'll send someone with a stamp of their own."

"Then they'll send someone."

She lifted the grown half off the contact plate. It sat in her palm like any other piece of shaped ceramic, which was what frightened her. She unsnapped the padded pocket on her tool belt and slid it in, and closed the flap over it, and pressed it flat with her hand.

Desmond pushed the slate an inch toward her. The empty field glowed.

She took off her stamp ring, set it on the bench, and slid it back toward him, unused.

"No," she said. "I won't certify that hatch."

Frost on Glass

The clamp arm came out of the dark on the cutter Harrowind's flank like a slow, deliberate hand, and Marisol watched it through the viewport of the exchange lock with her palm flat against the glass.

"He didn't wait," she said.

Behind her, Kenji was on his knees at the inner collar, his sleeves pushed up, a pressure gauge clipped to the ring and a torch in his teeth. He took the torch out. "Wait for what? You gave him your answer."

"I gave him a no. That's not the same as an answer he can't move."

The comm on the bulkhead clicked. Desmond's voice came through clipped and level, the voice he used for drills. "Tessaly Station, Harrowind. Clamping on the visitor hatch rim, outboard side of the exchange lock. All personnel clear the lock compartment. Repeat, clear the compartment."

Kenji didn't move. He was watching the gauge needle, which hadn't moved either. "If I leave the collar now, nobody's holding the inner side if their hatch shifts. You know what this ring's like. It wasn't built to take a load from outside."

"I know exactly what it's like. I certified it." She keyed the comm. "Desmond, the visitor half is seated in their rim. Their side of the seal. If your clamp bears on the rim, it bears on the seal."

"Then tell me where it doesn't."

She looked out at the craft. Under the station's work lights its hull had that pale, grained look of something grown rather than cast, and the haze still lay along it, faint as breath on cold metal. Where their hatch met the station's outer collar, the titanium half she'd machined sat in its cradle of living ceramic, a small bright crescent against all that pallor. She had lain awake two nights ago thinking about the angle of that crescent. She could have drawn it from memory.

"There isn't a place," she said. "Not one I'll put my name to."

A pause. On the cutter, he'd be standing at the arm controls with his crew behind him, every one of them wearing a dosimeter that had been chirping at them for days. She didn't hate him for that. She would have given a great deal to hate him for that.

"Noted," Desmond said. "I'm sorry, Marisol. Clamping."

The arm closed.

She felt it before she saw it, a shudder that came up through the deck plates and into her feet, then a second, harder one as the jaws found purchase. Kenji swore and braced both hands on the collar. The gauge needle twitched.

"It's holding," he said. "It's holding, it's..."

Through the glass she watched the crescent of titanium. The jaws hadn't touched it. They didn't need to. The ceramic around it flexed under the load, and for one moment she thought it would ride the stress out the way grown things sometimes do, giving and settling. Then a fine white line ran across the crescent's face from edge to edge, so neat it might have been scribed.

"Kenji, off the collar."

"Hang on, the inner seat's taking..."

"Off it. Now."

The seal split.

The noise inside the compartment was a shriek and then a roar, air tearing out through the gap in the outer collar, and the whole lock filled with a sudden white smoke that was not smoke. The moisture in the air froze as it fled. Ice crystals boiled past her face toward the breach. The wind of it hauled at her coveralls, at her hair, at the loose pens in her chest pocket, which went skittering across the deck and out of sight.

Kenji was nearest the breach. She saw him half rise, his hands still on the ring, and then the venting stream caught his left side and he went down against the collar with his arm pinned to the metal by the pull of it.

Her ears popped, then ached. The roar was already thinning, which meant the compartment was emptying. She knew the numbers for this without needing them. There was a little time, and then there wasn't.

She got to him on her hands and knees. The collar ring had gone white with frost, and so had his forearm where it lay against it, skin and sleeve both glazed. He was trying to pull away and couldn't; the cold had bonded him to the steel. His mouth was open and she couldn't hear what he was shouting.

She didn't think. She tore the padded pocket off her tool belt and jammed it between his arm and the ring, sawing it under, and the grown half inside it pressed through the padding against her knuckles, cold and still. Something gave. His arm came free with a sound she felt rather than heard. She took him under both shoulders and dragged.

The inner hatch was three body lengths away. It felt like kilometers. The air was going thin and strange in her chest, and the frost was racing across the viewport glass in ferns and feathers, blotting out the craft, the cutter, the arm. She got Kenji's legs over the sill. She got her own over. She hit the plate with the flat of her hand and the hatch swung shut on the last of the white roar, and the latch dogged home, and the station's air came back into her lungs all at once, warm and thick and smelling of machine oil.

Kenji lay on the corridor deck with his eyes squeezed shut, holding his left arm away from his body. From wrist to elbow the skin had gone a hard waxy white, and at the edges it was already flushing an angry red.

"Don't touch it," he said. His voice was hoarse. "Don't rub it. That's the rule, right? Don't rub it."

"That's the rule." Her hands were shaking. She pressed them against her own thighs. "Medical's coming. You're all right."

"You don't know that." He opened his eyes and looked at her, and despite everything one corner of his mouth went up. "You'd have to inspect me."

She made a sound that wasn't quite a laugh. She wanted to put her hand on his face and didn't, because it would have been the wrong moment and they both knew it, and because if she started she wasn't sure she'd stop.

The bulkhead comm was shouting. Desmond. "Marisol. Marisol, report. We read a breach, we read the compartment down to nothing. Who was in there?"

She got up and keyed it. "Kenji. He's out. Frostbite on his arm, maybe worse. He was on the collar because somebody had to be." Her voice came out flat and she let it. "Your clamp didn't open their hatch, Desmond. It opened mine."

A long silence. When he spoke again, the drill voice was gone. "Medical's on the way to you. I'm... understood."

Then, from somewhere on the cutter, the watch officer cut in, quick and uncertain. "Director, the visitor hull. Something's happening on the hull."

Marisol went back to the inner hatch. Its little port was clear, because this side of the glass was warm, but beyond it the compartment was a white blur of frost. She pressed her face close and looked past it, through the outer viewport where the ice was thinnest at the edges.

Along the visitor craft, light was moving. Not the haze, but something under it, a pale glow that pulsed in slow, even beats down the length of the hull, one after another. It was the same rhythm the grown half had answered her with on the first day, when it warmed in her hand. She had counted those pulses then out of sheer delight. She counted these now because she couldn't stop herself.

They stopped at thirty. A pause. Then thirty again, exactly the same.

"It's a count," she said into the comm. "They taught us their numbers on the first day, with the seal. That's thirty. They're telling us thirty."

"Thirty what?" Desmond asked.

The clamp arm jerked. On the outer collar, the cracked crescent of titanium tore loose from its cradle and spun away, a bright flake glinting once in the work lights. The craft had let go. The ceramic of its hatch rim simply withdrew, folding back into the hull like a closing mouth, and the jaws of the arm were left biting nothing.

Kenji had dragged himself up against the corridor wall. "Their orbit," he said. "Watch their orbit."

Slowly, with no flare and no light, the visitor craft eased off the station's collar. It moved the way things move up here, so gently it seemed not to move at all, until the gap between it and Tessaly was suddenly wide and widening, and it was sliding out and up, rising toward a higher, slower orbit. The last pulse of thirty went down its flank as it went. The haze went with it, pulling away from the station's hull like a tide drawing off a shore.

Behind her, on Kenji's chest, his dosimeter chirped once, then again, faster.

Marisol didn't turn around. She stood with her hand against the warm side of the glass and the frost on the far side, the torn pocket still balled in her other fist with the grown half inside it, and watched the craft grow small and pale against the dark, until it was only one more slow light among the others, drifting away.

Infirmary Light

The infirmary lights had been turned down to a dusky amber for the night cycle, and nobody had turned them back up. Marisol sat on the edge of the second bed with the dosimetry logs spread across her slate and Kenji's arm resting between them on a cradle of gel pads, wrapped from elbow to knuckles in white.

"You're reading it again," he said.

"I'm reading it differently."

He laughed, then winced, because laughing moved the arm. The skin under the dressing had blistered overnight in long pale welts where the collar ring had taken it, and the medic had said the words graft and maybe in the same breath. Kenji had said he'd take maybe. Marisol had gone and found the logs, because she couldn't sit and look at his arm and do nothing.

She turned the slate toward him. "Every alert since the craft docked. Here's the haze, here's the station counters climbing whenever it thickened. That's what Desmond saw. That's what the board saw."

"That's what I saw. I wore the badge."

"Now look after it left." She dragged the trace forward with her thumb. The line, which should have dropped like a stone once the visitors withdrew, did the opposite. It climbed. Not wildly, but steadily, a slow ramp that began the moment the haze pulled off the hull and had not stopped since. "Your dosimeter didn't start chirping because they were close. It started because they'd gone."

Kenji stared at it. His good hand lifted toward the screen and stopped. "They're farther away and we're getting more."

"Different, too." She split the trace. The readings under the haze had been soft and scattered, the kind of glow you got when something heavy and dense was soaking up a harder flux and giving a little of it back. The readings now were sharp, clean, coming from one direction. Up. Out toward the higher orbit where a small pale light had parked itself overnight. "The haze wasn't their exhaust. It was catching their exhaust. They built a wall around us, Kenji, and the wall glows a little, and we looked at the glow and thought it was the fire."

He was quiet a long moment. The amber light lay in the creases of the dressing.

"Desmond," he said finally, "is going to need to hear that from someone who isn't you."

"He's going to hear it from his own instruments."

The door hissed. Achterberg came in still wearing the cutter's flight jacket, the collar unzipped, a crease from a headrest pressed into one cheek. He'd been on the Harrowind all night; she could tell by the way he held himself, a little too straight, a man who hadn't let himself lie down. He looked at Kenji's arm before he looked at anyone's face.

"How bad?"

"Bad enough," Kenji said. "Ask the medic."

"I did." Achterberg's jaw worked. Then he turned to Marisol and held out his own slate, and she saw it was the same trace, pulled from the cutter's sensors rather than the station's, and the same slow ramp climbing off the right edge. "My people flagged it at shift change. I came to ask if you'd already seen it, but you obviously have."

"They were shielding us."

"I know what it looks like."

"Desmond."

"I know what it looks like." He sat down heavily in the visitor's chair, which creaked under him. "And I'm going to have to send that up the line to Thandeka with my name on it, and the board's going to ask why their security director boarded a ship that was standing between his crew and its own engine." He rubbed his face with both hands. "I'd do the same reading again. With what we had. I'd make the same call." He let his hands fall. "I'd be wrong again, too."

It was more than she'd expected from him, and less than she wanted, and she found she couldn't be angry at either part of it. He had sat in a cutter watching a counter climb near people he was responsible for. She'd sat in an inspection bay with a blade against something living because she wanted to understand it. Neither of them had asked first.

"What happens now?" Kenji asked.

"Station goes to shelter rotations. We keep the hab cores manned and everyone else sleeps behind the water walls until they're out of range or they come back." Achterberg looked at Marisol. "You said thirty."

"Thirty days. I think that's what they meant." She pulled the torn pocket from her belt and opened it on her knee. The grown half lay inside, pale and cool, the scraped notch along one curve like a bitten edge. It hadn't warmed once since the station's half spun away. "They pulled back for thirty days because we broke in. That's their rule, not ours. And they took the wall with them, because a wall that's been forced isn't a wall anymore."

"Or because they don't trust us to stand near it," Achterberg said.

"Same thing."

She turned the grown half over. On the inside face, where it had once locked against titanium, a set of fine ridges ran in a spiral. She'd measured those ridges on the fourth day and been so pleased with herself. They'd read the measuring as taking. She understood that now in her stomach, not just her head. You didn't take a sliver of someone's half of a promise to see what it was made of.

Her stamp ring was on her right hand where it had been since certification, heavy titanium, the inspector's mark cut into its face. Nothing boarded anything in this consortium without that mark. She'd refused it once and the clamp had gone in anyway.

She worked it off her finger.

"Mari," Kenji said.

"Hold this." She put the grown half in his good palm, notch up, and borrowed the medic's bench lamp, angling it low. The ring's bezel was close to the width of the scrape. Not exact. She took the small file from her kit and dressed the bezel down, slow strokes, checking against the notch, filing again, while neither man said anything. Titanium dust caught the amber light. When it fit, she pressed the ring into the scraped gap with her thumb and felt it seat. Her mark faced outward, set into the curve where her blade had cut.

Under Kenji's palm, very faintly, the grown half warmed.

Not a pulse. Just warmth, the way a stone holds the sun. He looked up at her with his mouth open.

"That's not forgiveness," Achterberg said quietly.

"No. It's a question." She took it back from Kenji, closed her hand on it. "Two seals. One half each. Ours is gone. So I'm what's left of ours."

Achterberg understood before Kenji did. She watched it reach him: the shoulders, then the eyes. "They're a long way up. The board will call it desertion."

"The board will call it whatever's useful. The Harrowind can put a pod on an intercept."

"And if they don't open?"

"Then I sit outside their door for thirty days with a repaired seal and a radio, and that's still more than anyone's done for them." She made herself look at him. "You'll have to sign the launch. I can't stamp my own."

He looked at the ring set into the grown half for a long time. Then he took his slate and pressed his thumb to it, and turned it so she could see the authorization go through, his name where hers would have been.

"Bay three," he said. "I'll have them fuel it." He stood, stopped at the door. "Okafor-Lind. If they show you how they built that wall, bring it home."

The door closed behind him.

Kenji was watching her. She sat down beside him on the bed, careful of the arm, and couldn't think of a single thing to say that would be the right size.

"You were going to ask me if I mind," he said.

"I was working up to it."

"Don't." He reached across with his good hand, caught the back of her neck, and pulled her down, and the kiss was clumsy and tasted of the infirmary's bitter tea and went on longer than either of them planned. When she drew back his eyes were wet and his voice wasn't. "I froze to their door yesterday because we didn't knock. Go knock. Go."

"Your arm..."

"Will be here. So will I." He let her go. "Thirty days. I can count too."

She left him in the amber light with the dressing white across his lap. In bay three the pod's hatch stood open, and the pressure suit hung on its rack beside it, already charged. Marisol tucked the warm half into the chest pocket, sealed it, and pulled the suit down from the rack. She stepped into the legs, shrugged the torso up over her shoulders, locked each glove ring until it clicked, and lifted the helmet over her head.

Hull Contact

The pod kicked free of bay three with a shove she felt in her spine and not in her ears. Tessaly Station fell away beneath her boots, its ring of lit windows shrinking to a bracelet, then to a smudge against Jupiter's banded glare. The burn that followed pressed her back into the couch for what felt like a long time. Then it let go, and there was only the quiet of a falling thing, the fans in her helmet, and the warm weight against her sternum where the pocket held the grown half.

The radio clicked.

"You're on the line we plotted." Achterberg's voice came thin and close, the cutter's relay adding a faint hiss under it. "Harrowind has you on optics. We're holding station well back. Nobody's closing on them. I wanted you to hear that from me."

"I heard it."

"Your intercept's long. You'll be coasting most of it."

"I've got a seat and a window. I've had worse shifts."

A pause, longer than the relay needed. "Kenji asked to be patched to the infirmary feed. I said yes. He's watching the same picture I am."

She closed her eyes for a moment. "Tell him the suit fits."

"Tell him yourself when you've got something to say. He'll want more than that."

She almost laughed. The pod's attitude jets ticked in short bursts, correcting, and through the forward port the stars wheeled slowly and settled. Somewhere ahead, too far and too dark to see yet, the craft hung in its higher orbit, outbound of the station and slower for it, the way everything up high moved slower. She had done the arithmetic herself, twice, in the infirmary, while Kenji slept. Climbing to meet something meant arriving behind it and letting it come back around to you. Patience was built into the orbit whether anyone liked it or not.

She drifted for a while in the harness and did not sleep. She took the grown half out once, inside the suit's pocket flap, and felt it through the glove: the ring she had pressed into its scar, the faint warmth that had not faded since bay three. It might have been her own body heat. She didn't think so.

The craft came up over the curve of the planet like a pale seed pod turned on its side. No lights. No haze now; it clung tight to whatever it had become out here, the skin dull and grainy in the reflected glow. The pod's proximity tone chimed, and she killed it.

"Okafor-Lind." Achterberg again. "Our dosimetry on you is flat. Whatever they used to keep off us, they're not pointing it at you. Or they're not pointing anything at all."

"They're waiting."

"Or they're dead in the water and we're telling ourselves a story."

"You don't believe that."

"I've believed a lot of things this week. Most of them turned out wrong." His breath crackled. "I'm required to say this. The consortium will log your departure from the pod as unauthorized contact. The board's confirmation came through an hour ago, before my report reached them. Light-lag. They signed off on a boarding that already happened and went badly. Rourke's trying to walk it back."

"Will she manage?"

"She's good. She's also a long way from the decisions." Another pause. "I won't stop you. I want that on the record too."

She matched velocity in short, careful pulses until the craft's hull filled the port and stopped moving relative to her. Close up the surface was not smooth. It had a grain like the inside of a shell, layered, faintly ridged, and here and there the ridges gathered toward small hollows. She knew one of them. She had helped cut its match on the first day, at the exchange lock, with the station's whole crew crowded behind her and Kenji muttering bad jokes into her ear to keep her hands from shaking.

The cradle was on the near flank, perhaps an arm's length from where the pod's nose had come to rest. Empty. The place the titanium half had locked into for three days before Achterberg's clamp split it.

She tethered off, purged the pod's cabin to vacuum, and watched the last of its air leave the hatch rim as a brief scatter of glittering ice, gone before it was a cloud. Then she pushed out.

There was no up. The hull was a wall, then a floor, then simply the thing in front of her. Her gloves met it and the contact was strange: not the hard ring of metal through the suit, but a slight give, the way old bone gives under a thumb, and then firmness. She held still. Nothing moved. Nothing opened. Her suit lamp threw her shadow across the grain, huge, and she dimmed it, then switched it off altogether and let the planet's dull light do the work. Bright lamps had been the first thing the boarding team brought.

"They're not opening," Achterberg said quietly.

"I didn't ask them to."

She worked herself hand over hand to the cradle. Inside it, the grown surface still bore the bright scars of the clamp, small crescents pressed into the shell where steel jaws had bitten. Around them the material had begun to fill in, slow and uneven, a healing she could see by the shade of it, paler at the edges. She touched one of the crescents and felt, very faintly through the glove, a tremor. The hum. The same pulse she had silenced with a scraper two days ago, back when she'd believed she was being careful.

"Desmond."

"Here."

"If this works, there won't be a second seal. Ours is gone, and I'm putting theirs back with my ring in it. That's one. There's no taking it out again. I want you to know before I do it."

"Irreversible."

"That's the point of it. Every lock I've ever certified could come apart if someone had the right tool and the right excuse. They need one that can't."

The relay hissed. When he spoke again his voice had gone rough. "My job's to keep the option open. That's all security is. Options." A breath. "Close it."

She opened the pocket. The grown half came out pale against her glove, the ring set into its notch like a filling in a tooth, the titanium bright where the ceramic had taken it. She turned it until its ridges lined up with the cradle's, the way she'd turned the first one, slowly, letting the shapes find each other instead of forcing them. Her hands were steady. She noticed that from a distance, as if they belonged to someone else.

The half slid in a finger's width and stopped.

She didn't push. She waited, palm flat over it, and felt the tremor under the hull rise to meet the tremor in the seal, two rhythms out of step, stumbling. For a long moment nothing happened and she thought, with perfect clarity, that she had come all this way to be politely refused, and that she would sit out here for thirty days anyway because there was nowhere else she had any right to be.

Then the rhythms caught.

The cradle tightened around the half. She felt it through her palm, a slow closing like a hand accepting another hand, and the pale edges of the healing crescents crept inward across the clamp scars. Her ring warmed until she could feel it through the glove's layers. The seam between the half and the cradle grew faint, then faded to the same grain as the hull around it, ridge running into ridge, until her fingers, searching for the edge she had made, found only shell and the small hard circle of her stamp sunk into it, flush.

She kept her hand there while the pulse beat steady under it, and against the hull's grain, beside her own glove, a seam she had not seen before began, very slowly, to part.
