She wouldn't be screaming any time soon. Ruby knew how it felt, knew exactly how much pain the vampire was in right now, it was a twisted form of torture to any being with such a complete aversion to the stuff, but one of the best tactics to shut them up as quickly as possible.
She watched the smoke, the steam, rising from burning lips and was about to move slightly forward again when Sam looked over to her, that look in his eyes that said he was unsure of himself again, understanding what he'd done, and why he'd had to do it but wondering was it right, was he right.
He was better than that, and the gaze she gave him in return showed just how much she believed in him. She didn't need to say it in words, didn't need to do anything. She knew that he would know. That he'd get it.
She twirled the knife offering it handle first to Sam. Holy water and her knife. Not a combination she'd ever tried for obvious reasons. It would hurt though. It would hurt a lot.
