Gwen: So go on then, how the hell did you end up in Cardiff?
Jack: This is Torchwood 3. Torchwood 1 was London, destroyed in the battle. Torchwood 2 is an office in Glasgow, very strange man. Torchwood 3, Cardiff, Torchwood 4 has kinda gone missing but we’ll find it one day.
Gwen: So you just fancied Cardiff?
Jack: There’s a rift in space and time running right through the city. The weevils didn’t come on a spaceship, they kinda just, slipped through. All sorts of things get washed up here, creatures, time shifts, space junk, debris. Flotsam and jetsam.
Gwen: Sounds like Cardiff…
