Matt Callahan, according to V2 storyline, was the younger brother of V2 finalist Ricky Callahan. Matt is featured in multiple posts during the V2 pre-game. He made his debut in "Usurper", where his somewhat love/hate relationship with his older brother is demonstrated. At the age of 16, Matt greatly looked up to his older brother, whereas Ricky saw Matt as a threat to his place in the Callahan family as the "golden child". Near the end of Ricky's stint in Survival of the Fittest, he seems to have deep issues with the way that he dealt with his brother and the feelings of resentment that he held toward him. One of Ricky's greatest fears before his death was never being able to apologize to Matt for his behavior during their final days together.
