"Dean might actually be about her type," Sam mused, only half seriously. "She likes the inhuman jackasses, right?" His eyes glinted with a wicked sort of light; he didn't really mean it. Except he did take a certain amount of pleasure in calling his brother names, whether they were entirely true or not. It was the only outlet for his anger he had at the moment. "If we cover him in glitter and give him a set of fake fangs..."
The truth was he wouldn't sic his brother on some stupid teenage girl, nor on anyone. Nor did he want anyone from Twilight anywhere near him or any of them. He grinned and accepted the push without argument. "As long as your love for glitter doesn't extend to sparklepires, I'm good with it."
He was engaged in the conversation, but he was still working. That meant he was paying attention to his surroundings. The vampire approached him from an angle just barely in his peripheral vision, but his senses picked up on it without him really processing it consciously, hair standing up on his neck. His expression closed over immediately, and he turned to face the newcomer, ready for a conflict if necessary, but keeping enough of his body turned toward Veronica to make it obvious that a third wasn't welcome. Sam thought he saw surprise in her expression when she saw his face, and then recognition.
"Hello," the vampire said, her voice a purr by comparison to the ice in Veronica's. Along with the way she was looking at him, it made his skin crawl, and tension became apparent in every line of his body. "Sam Winchester, isn't it? From the back, you look just like a friend of mine. But this is a pleasant surprise."
"I'm not your friend," Sam said. "And I didn't come here to make new ones. I'm a friend of the owner, I'm here to make sure nobody causes any trouble." His voice stayed calm, but his gaze was direct and not especially friendly. "We're not going to have any trouble, are we?"
