Clara: Only you would be friends with the Chairman of the Governors.
Doctor: Ian and I go back.
Doctor: Way back.
Doctor: Centuries back.
Clara: You go "way back" with practically everyone.
Doctor: Ian was one of the first humans I had ever met.
Clara: What? Really?
Doctor: Him and Barbara taught my granddaughter Susan.
Clara: You never told me much about her.
Doctor: Didn't think you'd be interested.
Clara: Don't you ever pop by to visit her?
Doctor: Who? Susan? I suppose I promised her one day I'll return again.
Clara: And have you?
Doctor: Well my eighth incarnation did.
Clara: But this one hasn't?
Doctor: No.
Clara: Well today's that day!
Doctor: I don't think now is the best time.
Clara: Is that what you've been telling yourself all this time? Come on, you said today is my choice and I choose this.
Doctor: I'm not even sure where she is.
Clara: Then we look. I thought you were the embodiment of adventure.
Doctor: Clara I'm not the same man as I was all those years ago.
Clara: Nobody is the same person they were when they're young. Doesn't mean we shouldn't forget those we knew. Besides I'd love to hear some of the stories that she has to tell.
Doctor: Which is exactly why we are not going.
Clara: Today is my choice.
Doctor: Anything besides that.
Clara: No.
Doctor: Aren't you supposed to teaching?
Clara: Aren't you supposed to care taking?
Doctor: I'm a Time Lord, I'm very capable of multitasking.
Clara: And I am a woman which makes me just as capable.
Doctor: I don't know what to do with you.
Clara: Take me to see Susan would be a good start.
Doctor: If I take you to see her will you shut up?
Clara: Maybe. It might keep me quiet for a short while.
Doctor: Calling you Ozzie today seemed to work too though.
Clara: That's because you called me it in front of the entire class!
Doctor: :)
Clara: Don't do that.
Doctor: Do what?
Clara: That smiley face. It's creepy.
Doctor: It's only a colon and a bracket. How is that creepy?
Clara: Because you're doing it.
Doctor: Ozzie :)
Clara: Call me Ozzie again and I'll smack those eyebrows right off of you.
Doctor: Right.. well as much as I love talking to you, I have actual work to do. Bye Ozzie.
Clara: Say goodbye to those eyebrows instead.
