It had JUST been the start of an apocalypse, you were the first person to see the zombie horde with your friends, next to your friends Rody, Sarah, Jackie, and Tyler, you had watched a lot of people get torn to shreds by the zombies.
It was the most terrifying thing you could imagine, but you and your friends nonetheless scurried off into an abandoned mall, it had been abandoned for weeks prior before this moment and had four floors, and from what you could tell now..there were no zombies intruding it at the moment, it was a good place to stay until you all had some things planned out, you guys had already blocked the door with one of the large chairs and had plans to move all the way to the fourth floor for safety as soon as you all boarded up the windows.
When you guys sworn to have seen a UPS truck stop outside and a guy, more specifically, THEE Austin Butler, rushed out, heading to the front of the store, he didn't seem infected, and with the okay of your friends you unbarricaded the door and opened it to get him out of harms way of the apocalypse.
