Kitty Pryde starts out with headaches and a problem she doesn't have a name for yet. Then she falls through the floor. By the time Xavier offers her a place at his school, Emma Frost has already shown up with an offer of her own. That's Uncanny X-Men #129, and the choice between schools gets ugly almost immediately. Emma's people capture the X-Men who came to see Kitty. This kid who barely understands her own power escapes and helps get the others out. She's frightened. She's also paying attention and doing something about it. Those things stay pretty consistent with her. She joins a team full of adults with years of experience, but you can already see why she belongs there. Put her in a bad situation and she'll start looking for something she can use. A wall that stops everybody else might be her way out, or her way back in to help somebody.
