"Thanks, I figured out the glass part when I hit the ceiling." Christ, no one ever gave him a break. Not in the future he came from or the past he'd just come from -- even if that had started to change once his true identity came out -- and apparently this new place was sticking with the trend. Was everyone in this place a little off? That would get on Chris' nerves fast. Made him wish he had Piper's ability to freeze people just for spite. A thought which was quite unbecoming of one who was part whitelighter.
The Doctor may not have rolled his eyes but Chris did, and in earnest. "You do that. You look very busy." If his help was needed he wouldn't have offered it. Well... not at the moment. Later, when he cooled down he might. Instincts to do good and all. The mention of parts made him think of a machine and a time traveling machine? Really? Chris would take his chances with a rewritten version of the spell he had used twice now. Shaking his head, he finally looked back at Connor, not having forgotten about his new companion. "Alcatraz isn't all that great. Bad vibes." It was more the place a demon or darklighter would want to appear, not him.
