KARVANISTA: You defile the sacred legacy of my forebears.

DAN: You don't look anything like four bears.

YASMIN: What are you doing?

DOCTOR: Checking all systems for malfunctions. Also, quick MOT check on my mind. Had a little glitch earlier.

YASMIN: What sort of glitch? You didn't mention it.

DOCTOR: You know what, Yaz? I don't mention everything.

YASMIN: No kidding.

DOCTOR: Are you being mardy?

YASMIN: What sort of glitch?

DOCTOR: A glitchy glitch. What does it matter?

YASMIN: Because I thought we were friends.

DOCTOR: We are friends.

YASMIN: Then why won't you let me in? What's going on with you?

DOCTOR: Nothing's going on with me.

YASMIN: Don't lie.

DOCTOR: Have we not had a good time together? Since Ryan and Graham left, have I not taken you to amazing places?

YASMIN: Of course, but...

DOCTOR: I thought I was showing you experiences of a lifetime.

YASMIN: You're hiding something. About him. About why you tracked him down in the first place. Tell me.

DAN: What's the point of being alive if it's not to make others happy?
