And Harry was no stranger to chasing people fleeing from him. He was going to aim really high of the kid at the drain pipe, because he didn't his rod or his staff with him at the moment and hitting the kid with an unaspected blast of pure magical energy seemed like a terrible way to make friends. He took two, very long strides (he was tall) toward the wall Mono was scaling, reached a hand out toward the top of the pipe, pulled together his frustration at this kid who kept running away, shouted, "Frozare!" and a solid piston of energy struck the pipe at its top bracket, sending the fastener and a bit of rock flying. Oops.

He was going to do his damnedest to make sure he was there to soften the kid's fall if he lost his grip.
