CAYLIE is the same age and they actually seem to have really similar personalities. Caylie's all about control and responsibility and taking care of other people. She was fairly shy in high school as well, though she compensated with a lot of nerdy tendencies. I feel like these two would get along well.
VIC primarily knows her from leading the Sentries and I think would like her for the most part. He appreciates responsible-minded team members. The only thing that might get them in trouble is her tendency to take on more than her fair share of responsibility - in theory, he totally gets and understands that, but in practice, he's learning that it doesn't fix the long-term problem of slackers and he worries that it might put her in danger. But mostly because he's the type to do it himself, too.
ERIC is a few years older than her and spent a lot of his adult life away, but he's been back for almost two years and they're probably friendly, even if they're not close. But they could be close! He's a very responsible person, but he has a really casual approach to being responsible. He's very charming and zen.
I don't think ASH, DEAN, or EVE would have much of a connection to her on their own, but I can't see any of them not getting along with her. ALEX doesn't need much medical help because of his healing factor, but he's occasionally needed some attention after a berserker episode, and they're both X-men royalty, so I'm sure they know each other well enough.
