DOCTOR: I think you came here with a plan, but you didn't expect to fall in love. But that's what happens.

GRAHAM: So, how long have you had a thing for Kira?

CHARLIE: How did you know about that?

GRAHAM: That's one of my superpowers, yeah. I can detect even the most subtle of social cues.

CHARLIE: Really?

GRAHAM: No! It's obvious!

DOCTOR: Ever hidden in a panelled alcove?

YAZ AND RYAN: No.

DOCTOR: You haven't lived.
