The mood had shifted, but Sam relaxed a little when the vamp moved away. Being recognizable was good for something, sometimes; scaring away bloodsuckers, for instance. It wasn't surprising that the vampire community knew his face, when the whole world did-- and he'd killed enough of them here in this world by now, too.
He relaxed enough that his expression had softened again when he looked at Veronica, but hers was still stoney. "I didn't like her either," he responded, wondering if she'd thought otherwise. More likely she thought that the vampire had liked him, which might not be untrue. He wasn't interested in wondering about it. "But staking her when she hasn't done anything wrong would cause trouble, and we're here to prevent that, not the other way around. Remember?"
She'd been reasonable, as vampires went. Most that would attend an establishment like this were reasonable enough, not that Sam trusted them any farther than he could throw them. Maybe if he knew them personally, he would, same as he'd come to trust Caroline and Angel, but they had fictional references he could check. Things still worked differently here than at home, though. Just because he didn't trust her didn't mean he had to be rude and stick a piece of wood through her heart.
Wanting to return to the easy conversation, but not wanting to make any assumptions about why her temper had flared up, he said, "You alright, cricket?"
