Emmett didn't really notice anything at all at first, until he was being hauled back, and separated from Diego's neck with a rather loud pop that echoed around his ears. At least, he let out a little growl, more instinctively reacting to being separated from his meal as he glanced up at Damon, blood dripping down his face.
"Diawl!" He hissed, the absolute nuclear option in Welsh insults coming out before he could control that, something he hadn't even heard his father use but maybe once. Glowering, he tried to push back against the hold on him, but didn't manage very far, struggling back against Damon as he tried to claw or spit his way out, even though that wasn't very conscious just now.
