SIXTH DOCTOR: Who said that? Who is that? Who's there?

SIXTH DOCTOR: Change. I feel it.

SIXTH DOCTOR / SEVENTH DOCTOR: Yes. I will regenerate. Our future is in safe hands.

SIXTH DOCTOR: I've had a good innings. All those lives I've lived... I hope the footprint I leave will be light, but apposite.
