MRS FLOOD: So much for the two Ranis. It's goodbye from me...

(She disappears.)

DOCTOR: We travel in and out of the slipstreams of time. Beatiful things can be forgotten and gone. But they still happened, somewhere. I think one thing remains. I love you. And I love you, Pops. That will never change.

FIFTEENTH DOCTOR: I don't want to do this alone.

(The Fifteenth Doctor walks to the TARDIS doors and opens them. He sees Joy's star)

FIFTEENTH DOCTOR: I'm never alone with you. Joy to the world! And that is exactly the word. This has been an absolute joy.

(The Fifteenth Doctor regenerates)

SIXTEENTH DOCTOR: Oh, hello!

THIRTEENTH DOCTOR: You've redecorated. I don't like it. Does it really need to be bigger in a room defined by its bigness?
