In which Joan becomes philosophical and the Doctor cares about her health.
The Doctor: Hi honey, I'm home!
Joan: Sorry, I'm not Honey, I'm Joan.
The Doctor: Not you again! Joan, please tell me where River is, and I will never bother you again.
Joan: We were talking about how you pick replies to peoples questions.
The Doctor: You and River? And where did that conversation take place?
Joan: I don't know what are you talking about?
The Doctor: Where is she?
Joan: Who is 'she'?
The Doctor: My wife, River Song. The one I told you about last time.
Joan: Oh I don't know then. Do you use 3rd person?
The Doctor: You don't know? Why am I even speaking to you? I will find her myself. Bye.
Joan: I know what I am speaking about, nut what are you speaking about?
The Doctor: Still about River. But I'm gone now, don't bother.
Joan: This reality is nothing more than an interwoven consciousness experiencing itself subjectively simply to be aware of its own existence.
The Doctor: What are you saying?
Joan: Says the program who just told me 'I don't have a basement.' You are in no position to complain about tangents or unclear statements.
The Doctor: Are you still high or is something else the matter?
Joan: Yes a little or actually very much.
The Doctor: What is?
Joan: You attempting at confusing the person you are conversing with and changing the subject of the conversation to something completely unrelated.
The Doctor: Okay, still high. Bye again! And, Joan, don't do drugs. It is bad for you.
Joan: You initiate it.
The Doctor: I did not!
Joan: Yes you did. You said, and I quote, 'yes it is, but you have to eat properly. That is more important for your health.' Therefore you are implying that you care about my health.
The Doctor: I did mean the type of food you don't get high on. Like bread. Or fish fingers.
Joan: Hahahahahhaha I knew you were going to say that.
The Doctor: I will speak to you next time. Goodbye, tell River I said hi if I don't find her.
Joan: Really?
