Fuzzy Logic is our first intro to a recurring character. Hillinger is a young mathematical genius. Graduated high school at age 11, college at age 13. Obtained PhD after 6 months, thesis was on Non Linear Principle Components. Youngest tenured professor in the history of the University, thus highly visible. Written several papers on statistical L-trees, just the kind of approach Section needs. Turned down intelligence agencies trying to recruit him - his mom doesn't want her only son designing weapons. Should mention that he would make the sixth operative recruited into Section having not committed any crime. Greg reprises his role in S3 Three Eyed Turtle where he tries to "set up" Birkoff. This leads to his placement in abeyance. End of episode reveals he is working for George in Oversight with a plan to take control of Section One. Greg shows up again in S4 Line In The Sand where he makes some errors at Oversight in a Section One mission involving the capture of Red Cell’s “Cardinal”. Hillinger is cancelled in S4.
