Sam grimaced as a dark clad figure threw themselves into the scene. It was only after a moment that he realized exactly who had joined them. Oh, if Dean was only here right now. Then again, he was pretty sure that Dean had met the bat.
"Do I look to be in a gaming mood?" he said, and aimed his gun at the witch's kneecap. He didn't like the idea of killing humans-even magic users. But he could absolutely incapacitate them. It was hard to focus on magic if one had to deal with a great deal of pain.
Tonight might have been someone's big night but as far as Sam was concerned, it wouldn't be the big night for this witch. Not if he (and apparently Batman) had anything to do about it.
