Oi! Space Man! Get yourself a new door! This one's full.
Donna, I like this door. Go find another door yourself if you're so desperate for one.
Right, I think I will. Where does the TARDIS keep spare doors?
...I don't think the TARDIS has a room of spare doors.
Wanna bet, Time Boy?
This is my TARDIS. I know that it does not have a room of spare doors.
Yes it does. Walk down the corridor and Turn Left.
What? Whaat? Whaaaaaat?
Clara suddenly had the urge to find Donna and either give her a round of applause for managing that, or hitting her because the TARDIS would listen to her and not Clara.
