Michael was a runaway that was currently traveling with the carnival and it had comeback to his old home in Miami,Florida.
Michael was walking home with one of his friends,when he walked in he saw walker's hand wrapped around his mom's neck he wanted to punch him so bad but knew he would put his mother and himself in even more danger.
After that day he decided that he should run away to keep his mom safe .He still made the effort to find a lawyer to help his mom when he came back remembering trying to help his mom escape the prison of their own home,fearing for her life.
Until michael met Kirstie,the girl he actually fell in love with.Kirstie is the one that lead him on the path of being a runaway for the carnival.
Michael and Angela are discussing the fact that he had never called nor involved the police with what seemed to be a horrible living situation with Walker.When in reality he has gone to the police many times but since he was a kid they believed Walker instead.
After the appointment he took a stroll down memory lane and wondered if Walker being dead now would help his mom.(Do you think he will ever find KIRSTIE?)
