Requirement of the Broken (Split & Glass fanfic)

'I really didn't want to go home, not after Barry. I didn't know if my mother was at home, or if she was still at work. I could only guess. Dad was probably home, watching TV or something. I hoped for the best, maybe he wouldn't even notice me... I feared two things: him being drunk and hurting me again, and him being completely sane and asking me questions about why I didn't come home earlier...'
A girl named Isla Nova meets one of Kevin's personalities, Barry - and her new life begins soon after. Her father is an alcoholic, and in all, her parents simply don't care about anything. She finds comfort in Barry, but later, a lot of things happen, and she meets the most feared persona - Dennis.
I do not own the characters from Split and Glass, they belong to Universal Studios and M. Night Shyamalan.
