Crap. Sam clung to his shotgun all the more tightly, shoulders tensing at the sound of a voice erupting from behind him. He'd checked the streets. Sam had even made sure that the store area had been clear before he'd focused himself on gathering the rock salt. But he'd forgotten the back room. How could he have forgotten to cover all his bases? Inwardly swearing, Sam turned around as ordered. His eyes soon met a somewhat familiar face, though Sam remained uncertain as to whether or not that face was currently being controlled by the person that it belonged to. Was she possessed? Her eyes weren't black, but for all Sam knew the demon inside of Shay could have just been hiding the black from him. He'd have to check and see - that was, if he didn't get attacked first.
"Who am I looking at right now?" Sam said sharply, not letting go of his gun. "Are you...you?" There were ways to prove if she was or wasn't. If she was herself, Shay would likely be willing to show him. Sam was more than willing to do the same for her as far as he was concerned. He didn't want anyone to get hurt between the two of them. Unless she was possessed. In which case he had no problems harming her whatsoever. Sam had enough holy water to make those sons of bitches scream.
...if that was even working anymore. Last he had checked, it was a practically useless tactic. Still, he had the salt too. And his gun.
