street rat from the Great White North, doing whatever he could to survive the cold harsh winters, pick pocketing, scamming people out of money, robbing corner stores... If you can name any petty crime Matt has done it. He doesn't consider himself "hard" but he definitely knows his way around and can hold his own in a fight if need be.
Tired of being stuck in the same place all his life, Matt made a split second decision to fly out to Chernarus which to him was some outback nothing place where he could maybe make something out of himself. It wasn't long after he arrived that he learned of the Infection too late. All transport was cancelled, nowhere to go and nobody to trust Matt is trying his best just to survive by himself. As with all people however, Loneliness can be deadly and he secretly hopes to one day be a big part of someone's life.
After almost bleeding to death from a Wolf attack, Matt, for the first time since he was in Chernarus, seriously thought about finding others to survive with.
In the end, Matthew chose the path of the merchant, belonging to no particular group he chose to do what he does best. Scavenging and finding something out of nothing. Which in turn leads to trade with many people, some good, some bad. Who's to decide.
