You do it out loud, and the sea, which does not care, happens to match.

Sprat comes home on a still dock. Paz comes home on the ladder, dripping, terrible jokes restored. The star-labeled tubes sit in a rack that Reed calls “not a handle.” Yuna’s grid, your travel times, TIDE’s bent straws, the near-neutral fish of Minnow—they stack. Stacking is the trick.

Vargas points at you when the last item is checked. “That’s a save.”

The surface storm can keep Gannet. You did not need a crane. You needed a ruler made of time, a density argument, and a door that was built to be a mouth. At nine hundred meters the mountain of water still sits on every hatch. It sat there the whole time you were clever, and the whole time you were correct. Correct is quieter.

Reed names a tank for the fun of it. Yuna sticks the paper squid so it can “see” the sample rack, which is silly and exactly right. TIDE logs depths that did not change: nine hundred. Sit. Work. Stay.

You look at the moon pool’s silver square and understand the joke of being a person in a bubble: the ocean is always trying to come in. You just keep the bubble honest, together, with numbers that match the water.

Later there will be forms. There will be a doctor shining a light in your ears and a person on Gannet who says good work in a voice that has said not good work to other crews. For now there is ginger tea, a bored computer, and a technician who is not a rumor.

You write three lines in your aquanaut log: I asked for the profile. I trimmed like a fish. I did not fly the glitter. It is not poetry. It is a map for the next kid.

THE END

What you learned: the deep is several problems at once—pressure on hatches, buoyancy as density, sound as a ruler, plumes that lie to lamps, and other humans. The choice that wins is the one that matches how water actually works, done with a checklist and a team. Guessing is louder. Thinking docks cleaner.
