Doctor: Sonic blaster, 51st century. Weapon factories of Villengard?
Jack Harkness: You've been to the factories?
Jack Harkness: They're gone now, destroyed. Main reactor went critical, vaporized the lot.
Doctor: Like I said. Once. There's a banana grove there now. I like bananas. Bananas are good.
Jack Harkness: It's a con. I was conning you. That's what I am, I'm a con man. Thought you were Time Agents. You're not, are you?
Rose Tyler: Just a couple more freelancers.
Jack Harkness: Oh! Should've known, the way you guys are blending in with the local color. Flag Girl was bad enough, but U-boat Captain?
Jack Harkness (to Doctor): Jack Harkness. I've been hearing all about you on the way over.
Rose Tyler: He knows, I had to tell him. About us being Time Agents.
Jack Harkness: And it's a real pleasure to meet you, Mr. Spock.
Doctor: Mr. Spock?
Rose Tyler: What was I supposed to say? You don't have a name. Don't you ever get tired of "Doctor"? Doctor who?
Doctor: Nine centuries in, I'm coping.
