Nightcrawler: I swear, that homie's lingo is so whack.
(about Forge as they wander through Middleverse.)

Nightcrawler: If you don't help her, this will haunt you for the rest of your life. Prove that you're not like her.
(to Rogue, in persuading her to save Mystique.)

Nightcrawler: It's raining furniture!

Nightcrawler: So, how far does this middleverse extend?
Forge: Stops just short of the girls locker room, isn't that a burn?

Nightcrawler: That was a delicious dinner, Mrs. Sefton.
Amanda's Mother: Well, it was sweet of you to offer to do the dishes.
Amanda: Oh, Kurt is very considerate. He gets good grades, too. And he has the nicest friends.
[Immediately before Toad crashes into the Sefton cottage and tries to steal Nightcrawler's portable holo-projector.]

Nightcrawler: Was? Got a scent?
Wolverine: Yeah... I smell fear.

Nightcrawler: Well, better do as he says. [Nightcrawler teleports, dropping Kitty's muffin, which cracks the floor tiles]
Shadowcat: [to Cyclops] Muffin?
Season 3

Nightcrawler: You did it, Rogue. The girl who shut herself off from the world just saved it.

Pietro: Cake walk. Our team can take a sauna. I'll get it myself.
Kurt: Not if I beat you there.

President: My fellow Americans - all my fellow Americans, human and mutant - I stand before you now to clear the X-Men of all wrongdoing in the giant Sentinel robot disaster. The real criminal suspect behind the Sentinel weapon has been arrested and charged. This has caught us all by surprise, but isn't reason for any of us to judge people solely by their differences. To put it as simply as I can, we need to learn more. We need to be open-minded. And we need to give this mutant question more time.

Professor X: Just in case you're curious: he turned out to be a very fine lad. [Leaves]

Professor X: That's all right, Kurt. Consider your probation over. (As Kurt celebrates, Xaiver turns toward the new arrivals) Yours, however, is just begining. And you can start by cleaning the X-Jet

Professor X: You've been carrying a terrible burden for many years, Mystique. Rogue's recent contact with you seems to have given her some of your darker memories; nightmares about a very unfortunate incident involving an infant.
Mystique: You're fishing. You know nothing.
Professor X: I know about your relationship with the boy, Mystique. What I don't know is what Magneto did to him. Why did you run that night?
Mystique: [Gets up from the desk and walks to the bookcase] Dear, dear Charles. How incredibly frustrating for you; to realise that that amazing mind of yours knows so very little, really.
Professor X: What were you two up to in that dreary castle? Was it worth the loss of your son?
[Xavier has hit a raw nerve. Mystique drops her book in shock, flooded by memories of what happened that night. Severely rattled, she turns back to Xavier.]

Professor Xavier: Todd Tolansky does indeed have the gift of the X-gene. He is welcome to join us, if he so desires.
Toad: [still mad at Kurt] The only thing I desire is blue-boy's fuzzy head!

Professor Xavier: Wolverine, it's Nightcrawler. The Rogue has his mind and his abilities.
Wolverine: This is my fault. I should never have left the little squirrel in charge!
