Matt has a brother named Richard, who is eight years older than him. Richard is a character made by one of my friends, Misha. At first I'd canonically killed Matthew in an old roleplay server, and while Misha was making Richard I commented that he sounded like Matthew. When I realized how much I missed Matthew as a character, and that I technically didn't rp the scene where I killed him and just left everyone to assume that's what happened, it got me thinking. I decided that Matthew had faked his death to escape that situation, and is now a fugitive of US government. AND since I never really fleshed out his backstory, me and Misha were able to create one together for the boys, who we decided should be brothers.
