Vylk admits to eating the man who wanted him to deliver the pen part to a Grace Field child, in order to give the children hope of escaping. When the part was connected, the pen displayed blueprints of the inside and outside of Grace Field houses, as well as how to make the medicine for the drugs that were used on Norman and his other drugged friends, and the way to the human world. Vylk and Emma (Demon) leave. While everyone is sleeping, it is seen that Vincent is calling a Grace Field via radio with Isabella picking up on the other side. Vincent says that he has information and is willing to get something for it.
