Sam had completely forgotten Joey was coming to meet him, he'd been preoccupied with dealing with Gretel, and then his thoughts had been consumed with the what ifs and potential outcomes if this turned out to be what he thought it was. So much so that he hadn't heard Joey approaching so he looked up a little startled when he heard her voice.
"What? Oh, no." He said, still sounding a little disorientated. He shook his head. "No it's not that, it's just....she's not exactly sick in the same way that everyone else is. Whatever she has it makes her dangerous, like some sort of rabid, feral animal." He sighed and got to his feet. "It's highly transmit table too. I had to restrain her."
