Alters
When Noel received Maya's phone call, he was ecstatic. He was still under the belief that he had no family left, and he didn't have many friends. For the few friends that he did have, he didn't want to tell them what he had done. Murder wasn't something to be proud of, and DID wasn't something that most people would understand. Even he could barely understand it.
It seemed, Nova wasn't the only alter he had. She was simply created recently to help him cope with his sister's death, but he actually had many alters who had done an amazing job at keeping themselves hidden from him.
Noel had always wondered why he'd have moments of amnesia and wake up in odd places sometimes. It didn't happen often, probably because the triggers for his alters had slowly disappeared from his life, but on the rare occasion that it did, he simply thought he was tired, or he had been sleepwalking. Recently, he even thought he was possessed.
