JAMIE: We're stuck here in this lift now!

DOCTOR: No, no it's the lift that's stuck, not us. Look.

(The Doctor points up at a maintenance hatch on the ceiling)

JAMIE: Hey, where does that lead to?

DOCTOR: Out into the lift shaft, I imagine. Quickly, on me back.

(The Doctor leans down)

JAMIE: You know something?

DOCTOR: Mmhmm?

JAMIE: You're a clever wee chappie.
