Ok to clarify the facts in Chapter 17:
There is a difference between a Creepypasta and a Creepypasta Child. You, are a Creepypasta. Jeff is(obviously) a Creepypasta. Your child will age faster due to genetic stimulation. The child will have the all the powers of both Creepypastas. Your child will have your demon powers, and Jeff's ability with a knife. They will not have Jeff's insanity, due to that being mental. Your mother wasn't a Creepypasta. She was an apprentice of sorts. She was almost killed by Slendy, but she pleaded with him to spare her. Slendy took her on, because he saw potential in her. If you have any questions, feel free to ask!
