[He's seen more enthusiastic agreements in his life, frankly, but Sam doesn't let that put him off for long. He snags a shirt from the floor, pulling it on over his vest and buttoning it up as quick as he can, following that with his jacket. As he's doing this, a thought strikes him, a memory of watching Who as a boy, and he turns to the Doctor.]

If you've got a... bollocks, what was it called? A binary induction plasma displacement detector. That ought to be able to pick up the TARDIS, shouldn't it?

[He takes his pistol from the shelf next to the door, tucking it into an inner pocket, and holding the door open for the Doctor.]

((OOC: The Doctor used this device to locate the TARDIS in 'Keeper of Traken,'))
