X-23 was happily lazing about in a window, just enough room for her to sit inside it and look out at the sky. Which is why she noticed someone launching himself at the window ledge and catching hold.

Well, that wasn't very usual, not for someone who didn't seem to have the ability to fly. Fliers usually were a bit reckless with the windows, it generally made her day more interesting in ways she rather her day was boring.

She waited a few moments, trying to decide what the right way to handle such an... odd, social interaction. Finally deciding she should say hello. She cracked the window, enough to talk but not enough he could get in without fighting her to open the window more, "Hello."
