TENTH DOCTOR: We must stop meeting like this.

FIFTH DOCTOR: (chuckles) No, we really must, I mean, it could literally tear the fabric of reality apart.

TENTH DOCTOR: Yes.

FIFTH DOCTOR: So we shouldn't.

TENTH DOCTOR: No.

FIFTH DOCTOR: Fun, though. At times.

TENTH DOCTOR: Yes. Yes, it was!

FIFTH DOCTOR: So that thing can scan for temporal anomalies but it can't open a lock?

TENTH DOCTOR: Totally different mechanics.

TENTH DOCTOR: You’ve got a hat on your hatstand.

FIFTH DOCTOR: Well , yes.

TENTH DOCTOR: I can’t remember the last time I wore a hat.

FIFTH DOCTOR: So what do we do now?

TENTH DOCTOR: About a hat?

FIFTH DOCTOR: About the fact that Paris and quite possibly the Earth has been taken over by Cybermen?

TENTH DOCTOR: Oh yeah.
