The guys over at DWSpoilers have reported a great little bit of script from the currently being filmed episode 12. The dialogue, which is between Craig and The Doctor, apparantly opens the episode.
The Doctor: Hello Craig, I’m back!
Craig: She didn’t!? How could she phone you!?
The Doctor: How could who phone me? Nobody phoned me, I’m just here. Oh, you’ve redecorated. I don’t like it.
Craig: Its a different house, we moved!… Doctor, what are you doing here?
The Doctor: Social call! How are you?
Craig: I’m fine.
The Doctor: I’m fine too, love to Sophie, bye!
