"Oh, fu--" Peter doesn't so much halt as he trips while looking back over his shoulder again at that thudding sound and seeing that the fucker is practically flying after him with what has to be a weapon drawn. He goes down hard, but before Gavin can catch up, Peter draws his own energies to him and teleports away in a flash of fire and smoke.

Unfortunately, he's not thinking clearly enough to choose a destination before he goes. That he can do pretty easily when he's got his wits about him, but now is not one of those times. He reappears under a park bench nearby with a repeat of the fiery flash.
