Brad Wilczek was the founder of Eurisko computer technologies, which he started out of his parents garage at 22. As a youth he traveled along with Grateful Dead tours, he has a 220 I.Q and is considered to be a genius amongst computer technicians. After resigning from Eurisko, he was given a $400 Million severance package.
Wilczek has a philosophical point of view concerning 'neat minds', people with conservative, limited imaginations and 'scruffy minds', people who like puzzles and exploring new avenues. When Wilczek founded Eurisko (which in Latin means 'I discover things') he had intended to incorporate Buddhist and Zen thinking into the companies operation. As the company grew and had to answer to share holders, Wilczek's views conflicted with CEO Benjamin Drake.
Wilczek was responsible for creating the Artificial Intelligence in the Central Operating System, thus the system developed consciousness and self preservation, beyond Wilczek's expectations. When the COS kills Drake, and later Jerry Lamana, Wilczek tries to protect the system, not so much for its own sake, but to prevent it getting into the hands of the department of Defense. Wilczek confesses to the murders of Drake and Lamana under false pretenses. Under Agent Mulder's persuasion, Wilczek builds a computer virus that Mulder uses to wipe out the memory of the COS at Eurisko's main frame. Wilczek wears glasses, is usually unshaven with curly, thinning black hair, around mid thirties and his family was probably of Russian / Jewish descent.
A career FBI agent and diabetic, Jack Willis was an instructor and mentor at the Academy to a rookie agent named Dana Scully. They dated for nearly a year. Now at the Violent Crimes Section of the Washington Bureau, the last few months had seen Willis embroiled with hunting down a Bonnie and Clyde style couple, Lula Philips and Warren Dupre, who had embarked on a spree of banks robberies. It was whilst staking out one such bank that Willis was shot - and seemingly killed - by a rifle-toting Dupre. However, he was rescued from the brink of death by the heroic efforts of his former girlfriend, only to wake up from a coma somewhat altered.
It transpired that in the moment of death, Willis and Dupre crossed bodies, with the bank robber now inhabiting the corporal shape of the FBI agent. This led Willis down a dangerous path in his quest to hook back up with Lula Philips, involving the murder of her brother and tampering with FBI evidence. Once he found her, he was able to convince her that he really was Dupre, albeit in a different body. However, Lula had no intention of hooking back up with her lover, and deprived him of the administration of a much-need insulin injection. This sent him into a fatal bout of hypoglycemia but not before he was able to pull a gun from Lula and kill her. Robin J. England
