So far, Gabriel hasn't been much bothered by the bloodlust. He's one of those who haven't been affected, and no one who has been affected has been anywhere near strong enough to pose a threat to him. That's mostly because he's not been interacting with people much, admittedly, preferring to sit back and watch, especially when it comes to those who've been affected.

But it's left him with the impression that it's not a big problem; in fact, he's almost convinced that the angels are too powerful to have been seriously affected. So, though he can sense something is certainly off with his brother, he doesn't let it worry him as much as it should. He does make an effort to stay out of his family's way, of course - no point risking a confrontation - but when by chance he runs into Raphael, he doesn't think the situation's so bad that he has any reason to just leave.

"'Sup, Raph." He's not about to start any kind of drawn-out conversation, of course. Certainly not anything emotionally charged. But he doesn't see any reason not to say 'hi' - even keeping in mind that Raphael seems a little ticked-off, being rude seems more likely to annoy him than being unobtrustively (and, alright, just a tad warily) friendly. "How's it hanging?"
