It wasn't jealousy that primed Sam's attention to the kiss. Or not mostly jealousy. He didn't share well, that was true, but they had agreements and women were fine. Hot, too, but that was a different problem for a different day.
What primed his attention was who she was kissing. Regina certainly didn't seem to object, and he knew she'd been with Molls the once, but as far as Sam knew, that was not an open relationship and what he knew of Dyson said the other man wasn't likely to be any better at sharing than he was.
There was nothing subtle about the way he walked over to Dyson and even less subtle about the way he jerked his chin toward the kiss that showed no sign of stopping, and was showing bad signs of leaking into the people still around. "Am I right in thinking a sorceress and a succubus making out in a room full of people who've been drinking is a Very Bad Idea?"
