The crew turn the ship around, back toward the Silver Sun when Cyriax falls victim to the green germ. Sheng & Leanella try to find a way to kill the germ. They find a chemical, but if they feed it to Cyriax, he will die. The crew search the whole ship for any other traces of the germ. Meanwhile, Squirt is lost, and Tane & Degenhardt find him in a room, but they get locked in, and the chemical that could kill them is released into the room. Squirt gets saved, and Degenhardt and Tane make it out alive, using their suits and oxygen. Pancha blames herself and feels guilty for Tane and Degenhardt almost dying, and she breaks up with Sheng, because he's a distraction.
