The Doctor: Parallel pilot compartments, bio-configured. Needs two operators of the same gene chain. That's why Solomon couldn't change the ship's course and neither have we. What?
Brian: We can. Me and Rory. We must be the same gene thingy you just said.
The Doctor: Brian Pond, you are delicious.
Brian: I'm not a Pond.
The Doctor: Of course you are. Sit down, both of you, lickety-split. Ship does all the engineering. The controls are straightforward, even a monkey could use them. Oh, look, they're going to. Guys, come on, comedy gold. Where's a Silurian audience when you need one?
