Idiot. What had he been thinking? He'd given fair warning that he was going to raise the fortress, too, but he hadn't even though to check to make sure Professor Bravo sought cover. Nevermind that he was expecting the man to just meekly go back into the shack where he'd been held captive for weeks, with his only hope of rescue about to storm the fortress. Of course he'd run.

He pushes the guilt aside for now, moving to follow the others in.
