His birth parents were extremely abusive to him and one day when Colin was out hunting with his dad, his dad shot him in the leg and left him to rot because he thought that Colin was just a failure, nothing more, nothing less, not to mention that Colin is gay and his dad is a homophobic, a couple hours later someone found him and rushed him to the hospital, eventually that man would become his adoptive father, his adoptive father was basically just a normal dad but anything was better than his old parents.
