Prior to 2251, Malcolm was one of many whose loved one had been murdered by Charles Dexter, the "Black Rose Killer." He, along with a group of others, not believing that the mind-wiped Dexter had perished in a fire as the authorities claimed, managed to track down Dexter on Babylon 5. Wanting revenge, they set about a plan to force Dexter (now living as a monk in a Trappist order by the name of Edward) to remember the crimes of his former life. First by hiring a Centauri telepath to break down the neural blocks, then by staging a number of incidents designed to evoke his forgotten memories. It worked, but, when the time came, the others couldn't bring themselves to inflict the final punishment on Edward. Malcolm had no such problem and took great pleasure in torturing and murdered an unresisting Edward. Malcolm was quickly apprehended and, far from feeling guilty, was proud of what he'd done, not even trying to deny it. After a short trial, he too was mind-wiped for his crimes and, now with a new personality eager to serve, was welcomed to the Trappist order by Brother Theo Ankises, who had personally requested Brother Malcolm.
