She was willing to follow through. Reassuring, but not enough to convince Sam that she wouldn't try anything halfway through. Eyes fixed on Shay, Sam twisted the rock salt container open and nodded. On three. Seemed fair. "Two," he continued. If she was one of his kind, he'd take her back to base to join up with the others. But if she wasn't...the hand that was gripping his shotgun was ready to do what was necessary to keep the potential demon that was wearing Shay from coming at him. He could handle one demon. Just so long as it didn't bleed all over him. "Three." On the third count, Sam immediately dumped the rock salt over his palm. It'd be a bitch for any demon that came into contact with it. He, on the other hand, didn't flinch in the slightest. Sam was no demon and even with the fucked up illusions running through their minds, Sam knew that Shay would at least be able to identify that the salt wasn't bothering him.
Once Sam was sure that what he had done would have been more than satisfactory, he flipped the rock salt container closed and looked off at Shay cautiously.
Sam was hoping that they could get this done quickly. Shay would make for a great extra pair of hands if she passed the test. She could help him haul some of this supplies back to the others. There, Sam would make sure that she stayed safe for as long as he could manage. He didn't know what was going on just yet, but he was sure as high hell determined to figure it out as soon as possible. This entire city was going under.
