In which we meet Joan.
The Doctor: Hi honey, I'm home!
Joan: Sorry, I'm not Honey, I'm Joan.
The Doctor: Sorry, wrong cell. Do you know where they keep River Song?
Joan: Have you checked on the table?
The Doctor: She's not on the table. I think she is in a cell. Unless she got restless, of course.
Joan: David bowie.
The Doctor: No, no. River Song. Nice hair, flirty, you know?
Joan: He indeed has! He has inspired so many artists and people!
The Doctor: No, I'm not talking about David Bowie! I am looking for my wife, Doctor River Song. You haven't seen her?
Joan: But he is god.
The Doctor: What crime are you here for? Annoyance?
Joan: Dunno, I am high. Have nothing to do. Heard of that.
The Doctor: Okay, I will not get any information out of you, I think. I will find her myself.
Joan: Well, that's nice to hear for a change. *laughs*.
The Doctor: Bye. If you see my wife, tell her you ruined her evening. I am done here.
Joan: I can't see you, I am just taking to you on my phone.
