ALLISON: What happened?

(Begins examining the Corporal's head)

CORPORAL: Sergeant Smith...

RACHEL: Is he all right?

ALLISON: No idea, I'm a physicist.

THE DOCTOR: He'll be fine! Rachel and Allison, I need your help.

RACHEL: (slightly incredulous) Sorry?

ALLISON: He said he needed our help.

RACHEL: That's what I thought he said. Get your hands off his scalp and come on!
