The background and character seems to explain itself, but I might as well put in the story for the people who don't know it as well. Purple Guy has just killed the children and is about to leave when he hears crying and whimpering. He chooses to ignore it, and continues walking. This was when he felt like he was being watched. He turned around but didn't see anyone - or anything - but he starts to question if all of this is real and that he isn't going crazy. The crying and whimpering continued to grow louder the longer he stayed in the pizzeria. He ran out of the pizzeria, screaming at the top of his lungs. Sorry that there's no shading, I kinda forgot to add that and I'm to lazy to add it in now :P
