Heath was following his friends and while loking at thehuge reactor he thought "this place used to hold life and now no one lives her" as he looks around he see's a building that that used to be a community pool as he looks at the open door way he saw something move from the door way he wasnt sure what it was maybe it was just the whole creepness of the town playing tricks on his mind but he was very curious and wanted to check it out, Heath then said " hey guys lets go check out that building" pointing to it.
