SARAH: It’s daft, but I haven’t ever thanked you for that time, and like I said, I wouldn’t have missed it for the world.
THE DOCTOR: Something to tell the grandkids.
SARAH: Oh, I think it’ll be someone else’s grandkids now.
THE DOCTOR: Right! Yes, sorry… I didn’t get a chance to ask. You haven’t, there hasn’t been anyone? You know?
SARAH: Well, there was this one guy. I traveled with him for a while, but he was a tough act to follow. (Laughs.) Goodbye, Doctor.
THE DOCTOR: It’s not goodbye…
SARAH: Say it, please. This time, say it.
THE DOCTOR: Goodbye. My Sarah Jane.
(They hug. The TARDIS disappears.)
