Mudge and his wife Sally shared a small studio apartment rented in The Sinclair Deluxe, a shabby apartment that leaked in the corners and smelled of rotten fish. He is increasingly addicted to Plasmids and spends what little money he has on SportsBoost and BruteMore under the justification of using it to get a job on Atlantic Express. He is apathetic to the effect the Plasmids have on him, dismissing the growths on his face as pimples. He also feels no blame on how he lost his last job by throwing a wrench at his foreman's head while high on Plasmids. Sally constantly nags and tries to talk sense into him, but to no avail. One night he decides he has had enough of her, and in a Plasmid-induced fury, kills her with an ice box. He immediately regrets his actions, because he no longer has Sally to pay the bills.
