ROSE: I think what the Doctor's trying to say is you may cut in.

(Rose extends her hand out to Jack to dance.)

DOCTOR: Rose! I've just remembered!

ROSE: What?

(The music changes from waltz to swing - Glenn Miller's In The Mood. The Doctor starts to click his fingers to the music and dance toward Rose and Jack.)

DOCTOR: I can dance! I can dance!

ROSE: Actually, Doctor, I thought Jack might like this dance.

DOCTOR: I'm sure he would, Rose. I'm absolutely certain. But who with?

(Rose chuckles and takes the Doctor's hand. They dance around the TARDIS while Jack watches.)
