Billy is running for his life. He makes it to a payphone and dials 911. Before he can answer the operator his world is turned upside down. Literally Billy is taken to a dark mirror dimension. He is screaming for answers when he is faced with his doppelgänger. This made me wonder. Does the monster not only have the power to possess a body but also take the form of someone that you trust? If it wants Billy to bend to its will it must earn his trust.
