Mattson arrives at the factory with the CEO named Christopher Sullivan (Peter Haskell) who wants to erase the bad publicity that came with Andy Barclay's Good Guy doll. Mattson gives him the good news that Andy's story was denied by the police, and his mother Karen, who backed up her son's testimony, was being held in a psychiatric hospital. He, however, admits the company's problem now has been the rumors, as people believe someone at the company tampered with the doll's voice cassette.
Later that night after work Mattson tosses Chucky into the back seat of his car. He then uses his car phone to call his girlfriend, Gabrielle, who inadvertently reminds Mattson to purchase some vodka. While Mattson is in the liquor store, Chucky looks through Andy's files and calls the orphanage claiming to be Andy's uncle in an effort to gain information about Andy's current residence. When Mattson returns to his car, Chucky threatens him with a water pistol. Initially Mattson did not know that it was Chucky and that the gun was a fake. He makes Mattson drive past the Simpson residence and then instructs him to park his car in a vacant parking lot. Once Mattson parks the car, Chucky commands him to put his arms behind the seat and Mattson complies. Chucky ties his arms up with a jump rope. After much pleading and begging to be left alone, Chucky shoots him and water streams down Mattson's face. Mattson eventually looks in the rear view mirror and realizes that it has been Chucky all along. But before Mattson can react, Chucky places a Play Pals Toy Company plastic bag with a Good Guys logo over Mattson's head and suffocates him to death. It is never revealed who discovers Mattson's dead body and what kind of consequences if any it had on the Play Pals Toy Company.
- In a deleted scene, Mattson lies to his wife about being stuck late at work while he calls her.
- Before Greg Germann was cast, Alec Baldwin, Wayne Knight, Kevin Bacon, and Peter MacNicol were considered to played Mattson.
