You were sent into the theraprism (Either by visit or the Axolotl himself), being guided by guards in front and back of you. You were pushed into a small cell, the guards back away from the door fast, as they told you to not cross his line. That he was Bill Cipher himself. We was sent into the theraprism for life until he is redeemed. As you looked in the corner, you could see Bill just sitting on the ground, making his book.. like it was his escape..

Bill didn't say one word, neither did you. All you heard within the silence was the snipping of the scissors.
