Amy finds another computer station and manages to access the ship's records. A Silurian appears on the screen. Of the ship's purpose, he says they wanted to "avoid the destructive impact forecast for our planet." The K-T extinction event? Dang, that ship is old.

The rickety robots lead the Doctor and Williams men through the ship. The Doctor is, as usual, happy as can be, while Brian worries about their impending deaths. "You're not gonna kill us, are you, Rusty?" the Doctor asks one of the robots. It takes great offense at the nickname. "You try being on this ship for two millennia. See how your paintwork does!" A triceratops wanders onto the scene, which delights the Doctor even more. He pets it and coos at it and calls it "Tricey." Tricey snuffles at Brian's crotch like an overeager retriever. "You don't have any vegetable matter in your trousers, do you, Brian?" asks the Doctor. "Only my balls," Brian says. Listen, I enjoy good scrotal humor as much as the next person, but: ugh. Brian is referring to the golf balls in his pocket, covered in a bit of grassy residue. Tricey gives Brian a big, gooey kiss, much to Brian's horror. He tosses a ball and Tricey goes chasing after it. The retriever analogy is complete.

Amy watches more of the Silurian's video and discovers that the ship is an ark. Riddell finds this all unbelievable. Nefi calls him an idiot for not believing what's in front of him. He threatens to give her a spanking. She whips out a dagger heretofore concealed in her bodice and slits his throat for the insult. Or maybe she just banters with him. Amy scans for Silurian life signs and finds none. Wondering what horrible fate could have befallen the Silurians, she searches through past and present scans and discovers a ship docked in the center of the buckyball.
