One SEAL, Ensign Monk, helps Bud use an experimental diving suit equipped with a liquid breathing apparatus to survive to that depth, though he will only be able to communicate through a keypad on the suit. Bud begins his dive, assisted by Lindsey's voice to keep him coherent against the effects of the mounting pressure, and reaches the warhead. Monk guides him in successfully disarming it. With little oxygen left in the system, Bud explains he knew it was a one-way trip, and tells Lindsey he loves her. As he waits for death, an NTI approaches Bud, takes his hand, and guides him to an alien city deep in the trench. Inside the city, the NTIs create an atmospheric pocket for Bud, allowing him to breathe normally. The NTIs then play back Bud's message to his wife and they look at each other with understanding.
