LAURENCE: I see.

DOCTOR: You don't understand the implications. I'm not a human being. I walk in eternity.

SARAH JANE: What's that supposed to mean?

DOCTOR: It means I've lived for something like seven hundred and fifty years.

SARAH JANE: Oh, you'll soon be middle aged.

DOCTOR: Something's very wrong.

SARAH: Doctor, I don't like it here.

DOCTOR: Something's going on contrary to the laws of the universe. I must find out what.

SUTEKH: Kneel before the might of Sutekh
