He's been hit by a virus or something similar, it's messed with his head, so going along with it isn't helping anything. Have you been hit by the same thing, Doctor? I left the TARDIS a couple of days ago, why would I be sneaking off it now?

Besides which, why wouldn't I be with Michael? I know you don't like him much, but in what universe did I ever hate him?

Geez, I'll be glad when this one's over...
