LAURA KINNEY
Literally doesn't get emotions or jokes or sarcasm, because she was cloned to be one thing, and one thing only - a killer - which she is very good at. That being said, she does wonder things, even if it scares her to wonder about them, and she fights with whether or not she has a soul or not - something she learned she did have back "home", but she doesn't remember that. She also occasionally cuts herself with her claws (which there would be warnings for if she were to do it) just to feel something that she understands.
She won't reciprocate very well, but she could use a friend or two. People who aren't put off by her weird ways and her lack of understanding of normal things. She'll also, as she always has, pick up on Wolverine's scent and connect it to her own and be rather protective over him. So if any of your characters were to attack him, they'd have to go through her first. (She knows he can take care of himself no matter what world it's in, it's just a territorial thing).
