ItFunneh, My AU

So I love the work that ItsFunneh does, and ItFunneh has always been a fun concept for me to work with. To explain my Au for those who don't know, ItFunneh never had a proper family. She didn't get enough love as a child, and she had this weird disease that no one Kane's how to deal with. Basically, the disease was what ended up turning the little girl into ItFunneh. The more trauma you experience, the worst the disease gets. Her parents chose to ignore the little girl, Kat, to a point where the disease got so bad she ran away. When she found Goldie, she used Goldie like the little sister she never had. But what happens when Goldie forgets all about Rainbow, and ItFunneh wants it to stay that way? Well to put it short, Rainbow slowly defends into madness. But Rainbow doesn't tell anyone about her problems because she doesn't want anyone else to get concerned with her issues.
