Wyatt didn't even think about what he had said. She was a human (for as far as he knew) and most humans can't just smell blood and know who it comes from. Hell, even as a werewolf, he had to have known Beth's scent to know it was her blood. And while he wouldn't admit it, he'd thought about Beth before. And he'd sat close enough to her to know what her blood smelled like. It wasn't that he even completely had a choice in that matter--in smelling blood. He could smell it all the time. He had tasted blood and he was aware of it's existence. He could hear it all around him, but it was something he kept to himself.
And the reason he more often kept to himself than making new friends.
At her question, he didn't know how to answer. Should he go ahead and tell her the truth or could he turn and just walk away? Looking over his shoulder, Wyatt looked down the hall. It would be easy enough to get away. But then again, if he walked away, he wouldn't get to hear what happened to her. Turning back to her, he took a breath and then decided to be honest. "I'm a were. I knew your smell from class and.. I knew it was you when I came across it." There. There, he could admit it. It felt like a heavy thing to carry.
