Farsight!
"So you've turned up again, have you?"
Yup.

Jewel?
"Extraordinary things only happen to extraordinary people."
Uncle Andrew?
"I mean, are they animals, or birds, or dwarfs, or what?"
Reep, actually.

"Don't I just wish I was big enough to punch your head!"
Yep!
Digory?
"So Narnia is no more."
Yes.
Peter or Edmund?
"It's all in Plato, all in Plato."
Nope, Tirian, actually.
Digory?
"Susan is no longer a friend of Narnia."
Yes.
Peter.
"Is he quite safe?"
Yep.
Digory?
"Surely. I love cats."
Susan, actually.
