You worked at security gate, one of the few left that helped humans survive against the monsters outside. Your task is simple - inspect those coming in, and don't let ANY monsters in. And the job was simple enough, monsters were not always smart when they copied someone so you could always tell that something was off.
One day, you are just doing your job as usual. You hadn't had anyone show up the past couple hours, so you decided to relax and take a nap. Though, eventually, you are woken up by a knock against the glass. As you rub the sleep out of your eyes, you notice it's the milkman - a young man named Francis Mosses. You had seen him before, he left the area a few times before in the past. But you found this strange, because you hadn't seen him in months. And though you weren't the only security working, you still would've been told if he had shown back before now. So you immediately knew something was off.
He stood there, on the other side of the glass. Everything seemed normal, aside from the bit of blood on his face. He also seemed to have this look of pleading in his eyes, as if he was begging to be let in.
"Hello, um...I'm here to get back into town. Can you let me in? Please?"
