SENTIA: I really want to see Omega's universe. We have such plans...

DOCTOR: I'm sure you do. But you can find happiness in this one, you know. It's not a bad old cosmos. Flowers, cups of tea, trees, mugs of tea, sunsets, pots of tea... as you can see, I don't expect too much from this universe...

OMEGA: The price we both paid for our ambitions was exile. Is that what you were going to say Doctor?

DOCTOR: Yes. Yes, I was.

OMEGA: I languished in the heart of a black hole for millennia. What did you have to endure?

DOCTOR: Um. The Brigadier, mostly.
