Aaron remembers pouring over every book in the town library's collection about mental health which, admittedly, was miniscule. He wanted to know how someone could go from slightly odd and a little quirky but mostly functional to full out hallucinations in what seemed like a short time. He had so desperately wanted to fix his mother, to save her somehow, but the only useful information he found was about multiple personality disorder and how it manifested. He didn't think it was relevant then, but he kept that knowledge like he did everything else, locking it away for further study at another time.

"Nah. Saw an old movie once. It was called uh - Dave and Lisa! No. David and Lisa. The girl had other personalities."
