Being as wired as he was to his computer (and the Photoshop installed in it), even if Harley hadn't been out and about when the first demon attacks started, he still would have heard about them eventually. And he wasn't amused by them then, either. "I was under the impression that the whole world got to meet demons, not just our sleepy little town," he pointed out. "We'll go for the high school. At least they'll be able to tell us where to go if nothing else, right?"
As if to remind them that, oh hey, that demon was still back there, the demon caught up enough to swipe at the back end of the car - and took off Harley's bumper with it. Harley turned the wheel hard to keep them from going off the road, knuckles beyond white at this point. Now the riflebird in him was freaking out, wanting away from that thing and away from it now.
