Pyro was a man of many skills, and this happened to be one of them, and one he was at least a little proud of. The acrobatic ability to do all the things at once wasn't exactly easiest. Nonetheless, John was happy to focus on his task and keep the pressure going and enjoy what he was doing.

He finally commented as he drove himself into her fiercely.
