Rose Tyler: Can't you come through properly? The Doctor: Then the whole thing would fracture. The two universes would collapse. Rose Tyler: So?

Rose: My mum's here. The Doctor: Oh, that's just what I need! Don't you dare make this place domestic! Mickey Smith: You ruined my life, Doctor. [the Doctor turns and looks at him, irritated] They thought she was dead, I was a murder suspect because of you! The Doctor: [looks at Rose] See what I mean? Domestic! Mickey: I bet you don't even remember my name! The Doctor: Ricky. Mickey: It's Mickey! The Doctor: No, it's Ricky. Mickey: I think I know my own name! The Doctor: You think you know your own name? How stupid are you?

Cyber Leader: Daleks, be warned. You have declared war upon the Cybermen. Dalek Sec: This is not war - this is pest control! Cyber Leader: We have five million Cybermen. How many are you?
