Sam scrubbed a hand over his face, the adrenaline of the previous hour or so was beginning to ebb and leave exhaustion in it's wake. He sighed and met Joey's eyes. "I've seen it before. Or if not it then something very like it. She's not gonna be concerned about food right now and she's not gonna need to sleep. If you try to have any kind of contact with her, even just a visual across a room she will attack you with terrifying determination. That's the only basic need she has right now."
Sam glanced over his shoulder at the door to Gretel's apartment, a vaguely sad expression on his face, though that could have been the tiredness creeping in. "If she bites anyone or scratches anyone and her blood gets mixed with theirs then she'll infect them too so we can't risk her having contact with anyone. Not even for food. If we dangle a person in front of her she won't let the fact that she's restrained stop her." He looked back at Joey. "It's basically a waiting game to see if things go back to normal because if they don't the only way I know to stop it is to....." He couldn't finish that thought, not out loud at least, not yet.
He sighed again. "I could be wrong, believe me I hope I am, but I wouldn't want to take the chance. I think right now our priority has to be making sure we're all safe from her. There's not much we can actually do for Gretel right now." His shoulders visibly slumped when he'd finished talking, as if it had been an effort to voice all of that. His eyes caught on the blood she'd smeared on the wall, he made a note to clean that up. Last thing they needed was Gretel contained and people getting infected anyway.
