Jackie and Mickey in “World War Three”

We've got to tell someone.

Who do we trust? For all we know, they've all got big... bog monsters inside of 'em! I mean, this is what he does, Jacks. That Doctor bloke. Everywhere he goes, death and destruction. And he's got Rose in the middle of it.

Has he got a great big green thing inside him, then?

I wouldn't put it past him. But like it or not, he's the only person who knows how to fight these things.
