I saw a hint of Danny/Scooti, actually. And other people were getting the lesbian vibe from Ida/Scooti, although I thought they looked like they were related, myself. Orgy, anyone? :-P

Zach said 'on behalf of the Torchwood Archive'. Perhaps the Archive is a database of alien species that can threaten Earth?

Anyway, the Doctor won't be seeing them in Torchwood because he isn't supposed to appear in the spin-off (did they rule out cameos, though?)
