Ryan blinked. That was certainly a much less formal greeting than he'd been expecting; Professor Urie - Brendon - was a great deal younger and decidedly less formal (and less fusty and proper) than he'd been expecting. That, more than anything, really brought home to Ryan for the first time since leaving England that Hogwarts - hell, Wizarding Britain - had changed irrevocably in his absence. The young man was practically bouncing on the balls of his feet with enthusiasm.
Ryan reached out and took his hand. "Ryan," he offered, and it felt strangely relieving. He smiled shyly. "Thanks. I hope I haven't kept you waiting long - I'm kind of late, I know. God, it feels so strange to be back at school. I feel like I'm about to get detention for being out of uniform."
