Jimmy, The Doctor and others in “The Rebel Flesh”

Yes, it's insane. And it's about to get even more insanerer. Is that a word? Show yourself! Right now!

Doctor! We are trapped in here and Rory's out there with them. Hello! We can't get to the TARDIS and we can't even leave the island.

Correct in every respect, Pond. It's frightening. Unexpected. Frankly, a total utter splattering mess on the carpet. [a Ganger copy of the Doctor steps out of the shadows - identically clothed, but with the gelid, half-finished face of the recently-formed Flesh] But I am certain — one hundred percent certain — that we can work this out. Trust me. [straightens his bow tie] I'm the Doctor.
