chunk: Lindsey is sent in dive gear to retrieve some oxygen bottles from a damaged portion of the rig to give the crew enough time to wait out the storm. While working, she's accosted by a small, maneuverable pink/purple device, followed by a much larger one. Before she can take a picture as proof, the large craft zooms downward into the trench, leaving her to take fuzzy, smeared pictures of the smaller one following it. She coins the term "non-terrestrial intelligence", or "NTI". As the crew struggles against the cold, they find an NTI has formed a living column of water and is exploring the base. Though they treat it with curiosity, Coffey is agitated by it and cuts it in half by closing a pressure bulkhead on it, causing it to retreat. The crew becomes convinced that Coffey is suffering paranoia from high-pressure nervous syndrome. Spying on him through a remote operated vehicle, they find he and another SEAL are arming the warhead to attack the NTIs, and race to stop him. Bud fights
