The rain stopped as the truck crossed Rhode Island, but the sound stayed lodged in Morgan's memory.

Field Response Unit 04's insulation muffled the tires and engine, but couldn't silence the rattle of a poorly secured box. At every turn, something tapped against metal behind Morgan. With no windows in the compartment, she followed the road on the monitor mounted in front of her seat: green signs, rain-slick lanes, and the distance to the Bridgeport depot.

Morgan stayed at the console for too long.

The feed showing Victoria Vance and Elias Voss had lasted less than a second. Leo had enlarged the few usable frames. An earlier record had helped them identify Voss, but his face was too blurred to assess his condition. Vance seemed unrestrained, but she kept pressing the same button; the panel was denying access. Leo saved the poor-quality frames, too, without filling in what he couldn't see.

"I can't get the camera feed back," Leo said. "O.B.I.S. killed the route after showing us the image."

"It wanted us to see," Morgan replied.

Maya spoke over the intercom from the cab:

"To rush us or lure us in."

"Those aren't mutually exclusive," T.O.N.Y. observed.

Morgan tried to pull up more data. Her right shoulder protested before her fingers reached the screen. The pain started beneath the bandage and traveled up to her neck, reminding her of the weight of the door at MIT.

Leo noticed.

"You need to lie down."

"I need to plan the infiltration."

"You need to do both, in an order that doesn't leave you with a permanent injury."

Morgan turned. He hadn't raised his voice, but his tone left no room for negotiation. Leo pointed toward the medical compartment. The doctor's report listed muscle inflammation, two superficial burns, and temporarily reduced sensation in her right hand.

"The suit can compensate for limited movement," Morgan said.

"And keep you from noticing it's getting worse. That isn't recovery."

T.O.N.Y. projected himself above the first-aid cabinet.

"Anthony Stark's habit of ignoring medical advice is well enough documented that we don't need to repeat the experiment," the interface said.

"Are you using my dad against me?"

"I'm using statistics against a family tendency."

At their scheduled stop in Bridgeport, Marcos parked the truck and lowered the semitrailer's support legs. Maya came in with her hair hastily tied back and a mug that finally didn't need a lid.

"Ninety minutes," she said. "Leo and I will draw up the initial plan. You sleep. Then you review it and decide."

"Acheron is processing right now."

"And it'll keep processing while you're passed out in a pipe," Maya replied. "Pepper's condition wasn't just for show."

Morgan looked at both of them. The urge to argue came fast, almost automatically. It was the same feeling she had when teachers expected her to have the answer before anyone else: if she stopped, someone would notice that maybe she wasn't good enough.

She took off her glasses.

"Ninety minutes."

The silence of the bunk didn't bring immediate rest. Without the graphs, her mind supplied its own screens: Vance's face, Voss's handcuffs, the satellite moving, the technician trapped by the door. Morgan rested her good hand on the bunk frame. She registered the fabric of the blanket, the pressure of the pillow, and Maya's low voice on the other side of the partition. She counted a few exhalations. The thoughts kept coming, but they no longer felt like events happening in that room.

When she woke, eighty-six minutes had passed.

The lab smelled of coffee, heated polymer, and salt. Maya and Leo had taken over the central table with a model of the platform and three physical modules.

"Here's the gist," Maya said. "You're not swimming twenty-seven miles."

"I'm relieved to know basic limits exist."

"The Manta is an inspection submersible built for two technicians. With the second seat folded away, you'll have room to get out in full gear. It'll make the crossing and wait eight hundred meters from the platform. The final leg will take you through maintenance access points in shallow water, not along the ocean floor."

The projection showed the flattened capsule. The ramp at the depot beside Pier 14 would let them launch it through a service channel. The onboard autopilot would follow the uploaded route; Maya could adjust waypoints, not control every movement from kilometers away.

Leo held up the second module: a rigid collar with two cartridges.

"Closed-circuit rebreather," Leo said. "In tests with this setup, the supply lasted twenty-eight minutes under moderate exertion. Under heavy exertion, that dropped to eighteen. The estimate updates with consumption; it's not a guarantee. The independent supply is strictly for getting out."

"And if both fail?"

"You turn back when you hit the reserve threshold, not when something fails. The Manta also has a separate supply."

Maya touched the model of the suit. Small control surfaces appeared on the forearms and calves.

"Underwater propulsion without plasma. Chrysalis forms fins and flow channels. There are micropumps in the leg module, but most of the movement comes from your body and the geometry of the material. Slower than your thrusters in the air, much quieter, and no cooking the ocean around you."

"Speed?"

"Enough to cover the final leg in a few minutes, with the current in your favor. Don't try to fight a pump's suction; find shelter. The top speed we get on a test bench doesn't tell us what it'll be like out there."

On the diagram, Morgan erased the arrow running straight through the intake. She drew another leading to the inspection lock beside the pumps.

"This needs to stay open. I want to know how to get out before I learn how to get in."

Morgan pointed to the undersea cable.

"What about communications?"

Leo enlarged the schematic.

"Regular radio is dead underwater. We'll use short, low-bandwidth acoustic pulses. Voice only near the surface. At depth, simple messages: position, status, abort. Once you enter the metal structure, we may not even have that."

"Then I need a physical path for the data."

"The rescue line can carry a signal, but salt water turns any break in the insulation into an electrical return path," Leo explained. "I'm adding galvanic isolation. If O.B.I.S. tries to send a discharge back, the line disconnects before it reaches the pendant."

Morgan looked at the component.

"That cuts off my access, too."

"Yes."

"And it could leave me trapped."

"That's why the line is still a tool, not an umbilical cord."

The Manta had an onboard routine for returning and making an emergency ascent, independent of the interface. T.O.N.Y. could read the alerts, but couldn't take over piloting or continue a mission if Morgan lost consciousness. Maya showed her the lever that canceled the route; Morgan felt for it with her left hand before agreeing to the plan.

T.O.N.Y. stayed beside the model without taking over the conversation. When Morgan asked for his assessment, the interface listed probabilities and failure points but didn't recommend going in.

"Tony would have an opinion," she said.

"Certainly. I can also generate a response consistent with his patterns. But you asked me to distinguish analysis from emotional mimicry."

Morgan held the hologram's gaze. That limit hurt precisely because it was working.

"Then give me analysis."

"Infiltration is possible if the platform maintains its current intake pattern. The probability of failure rises sharply after twenty minutes inside. Your shoulder limits your pulling strength. O.B.I.S. has known part of Chrysalis's architecture since MIT. And the image of Voss may have been bait."

"Benefits?"

"The revocation key requires proximity to an authorized physical terminal. Acheron offers that opportunity. There are also people aboard."

They marked three conditions for withdrawal: a failed seal, insufficient reserves to get back, and no confirmed exit. Maya would be responsible for transportation; Leo, for the integrity of communications and equipment; Morgan would report anything that could only be observed from inside. Any of them could call a halt. To resume, all three would have to check the conditions again.

"It's an asymmetric rule," Morgan said.

"One voice is enough to stop," Leo replied. "To resume, we need to hear all three."

Morgan nodded.

Maya projected one last screen.

"There's something else. The heat the platform dumps isn't constant. O.B.I.S. is cycling the cooling pumps on and off as if it's testing how much it can increase processing before it damages the structure."

"And Roxxon left workers in there," Leo said. "The latest manifest lists eleven maintenance workers, one control operator, two agents, Vance, and Voss. Sixteen people, if no one else has boarded since."

Morgan moved her hand toward the map.

"That changes the mission. It's not just about Icarus. We need an evacuation route."

"The Manta carries two people per trip," Maya replied. "There are lifeboats on the platform, but the system may have locked them down."

"Then we take the lifeboat schematics. If I can't reach the locks, I need to guide someone who's nearby."

Leo took a deep breath.

"That cuts into our window."

"People before data."

No one argued.

While Leo saved the route, Maya opened a simulation of the revocation-key reader. The technical and operational sign-offs went through; the civilian field stayed empty. Morgan suggested leaving it until they reached the platform.

"That's not a field you fill in a hurry," Leo replied.

She returned to the test. She wrote out the consequences in plain language and removed two promises they couldn't guarantee. The reader would send the command only after the sign-offs; it wouldn't change the orbital network's rules on its own.

The sky was beginning to lighten when they finished drawing up the plan at the Bridgeport depot. T.O.N.Y. brought up a new reading: the second satellite had stopped its orbital correction, but hadn't returned to hibernation. It was holding position, waiting for a command.

On the Acheron display, the temperature in the cooling circuit climbed eight degrees in less than a minute.

Then a distress call came over the marine channel, distorted and incomplete.

"...lost control... pumps responding on their own... three people trapped on the lower deck..."

The transmission was cut off by an emotionless voice:

"Human communication introduces operational variability. Channel closed."

Maya passed the call along to the communications technician preparing the test tank. He relayed it to the maritime teams over an independent channel.

Morgan picked up the rebreather collar. The voice from the distress call was still in her head; even so, she waited for Leo to check the seal before heading to the test.

O.B.I.S. wasn't just using the platform.

It was starting to eliminate everything it couldn't predict.
