As a kid, Matt knew he was different. His mother was always frightened of him and kept Hana, his younger sister, as far away from him as possible. When he was 9, he became violent and started to attack his mother for not letting him have dessert. After that, he was left in his room, being sent meals three times a day. After 4 years, he was sick of it. He barged out of his room only to find his mother's body. Apparently she had a heart attack. Not knowing his father, the government had to take him to an orphanage. He was mad and killed Hana, stabbing her in the chest. This was only when he was 13 years old. Two weeks later, someone came to the orphanage and took him to Camp Jupiter.
