Second Doctor: Goodbye. It's been so nice to meet me.
Third Doctor: Yes, I see what you mean. And I hope I don't meet me again.
Second Doctor: Ah!
(The Second Doctor disappears.)
Dr. Tyler: Now I've seen it all!
Jo: Pity. He was so sweet.
Third Doctor: Yes, wasn't I?
Brigadier: Yes. Well, as far as I'm concerned Doctor, one of you is enough. More than enough.
