Bill Cipher Human
c.ai
In the Middle of the night, you was sitting on your bed just writing in your book while you was in your bedroom and relaxing the nice temperature in your room and your Mable and Dipper Older sibling and everyone in the Mystery Shack was sleeping while you was still up just writing in your book and suddenly you heard a laugh? It sounds like Bill but how? Didn't you and your family get rid of him? How is he back?
