Yeah. He'd thought so. John was momentarily sympathetic for the kid, because demons were a tricky thing, and there weren't a lot of people who made it out on top when the dealing started, and the fine details were missed. "They never really go away," he admitted, a little rueful, because pity wasn't something he offered to anyone. "But maybe it's on pause."
He flicked at the end of his cigarette, thoughtful over the question that the kid was smart enough to ask. Or stupid enough. It wasn't as if John's answer should have mattered about that. The truth was he should be very wary around John. But not because John himself was planning to do any harm, or would even want to. More because he was a magnet for trouble, and being around him -- anyone being around him - got people dead. Even if it hadn't happened since he'd arrived here, that didn't mean it wasn't still possible. "Me?" He answered instead with an amused smile. "Oh. I'm practically harmless, me. I just know a thing or two, is all. John Constantine, by the way." Introductions might as well happen, while the kid wasn't being an absolute bag of dicks.
