They're all roommates in the X-Center now, but Pixie was living in that warehouse just a few short issues ago. It's like the X-Men went to Wales and said "Megan, come back to America with us. We're moving to San Francisco on the other side of the country, where you should feel at home with the miserable weather. Oh, but we're not giving you a place to stay right away. Emma and I will be living in a luxurious penthouse in the middle of San Francisco, but you might have to find a old abandoned building in the hood to squat in with a bunch of horny college dudes. Good luck."
