[seeing Cyclops, Jean Grey, and Storm seemingly alive, Logan steps into Professor X's office]

Wolverine:
You did it.

Professor X:
Did what? Logan, don't you have a class to teach?

Wolverine:
A class to teach?

Professor X:
History

Wolverine:
History. Actually, I could use some help with that.

Professor X:
Help with that?

Wolverine:
Well, pretty much everything after 1973. [The Professor is surprised.] I think the history I know is a little different.

Professor X:
[reads Wolverine's mind and understands what he went through] Welcome back.

Wolverine:
It's good to see you, Charles. It's good to see everyone.

Professor X:
Well, I had a promise to keep. You and I have a lot of catching up to do.

Wolverine:
Yeah.

Professor X:
What's the last thing you remembered?

Wolverine:
Drowning.
