Matt is Eliot's son, who is interested in Jenny, and tries to play a prank on her that is called "killing," a game which involves squirting someone with a squirt gun in the presence of just one witness. His first attempt is completely thwarted by a series of bizarre coincidences, and he is seriously beaten by both Anna and Jenny, who quickly apologize for their actions when they realize the gun he was carrying was not real, and that he was only playing a game. He is also friends with Andrew, who has been assigned to witness his "killing" of Jenny. He has something of a crush on Jenny, and she returns the feelings by allowing him to "kill" her the next day. This attempt is again thwarted by a person who actually carries a firearm and mistakes the game for an actual crime. He escapes with Jenny and returns with Monica and Walter to the Herk residence, which is visited by Snake and Eddie shortly thereafter. He comes with Monica to the airport and plays an important role when it comes time to rush towards the plane, pushing Monica on board and hiding in back of the plane with her. He is described as intelligent, but having nothing to do with academic activities. He dates Jenny briefly after the incident on the plane, but the two decide to become friends, since they are technically step-siblings after their parents get married.
