Oh, but they could. Case in point: the man in track shoes and jeans who'd appeared from a side street with enough speed to stir up the papers on the ground. He'd been following another of the winged creatures, and he was frustrated: frustrated because not only had it gotten a shot off, but it had also managed to outpace him. That never happened.

"I heard an explosion." Pietro's tone was matter-of-fact. As far as he was concerned, he would deal with whatever trouble had prompted the blowing-up, and then he'd resume chasing the accursed winged things.

Of course, he hadn't planned on running into Ace. Logically, he realized that something was wrong. He was used to feeling strongly about Ororo, but even that had taken time. Pietro was not given to spontaneous strong emotion, which was part of why he had no idea what to do. So, he stood still. And stared; rude, but for someone so fast, his brain was moving quite slowly.
