That mention of 'The X-Files' in connection to the second season opener for 'Fringe' is further re-inforced by the presence of Ken Camroux as the Senator who was in charge of the sub-committee hearing. He was involved literally right from the very beginning of 'The X-Files'!
He was seen in the 'Pilot' episode as being in Blevins' office when Scully is given her marching orders to team up with Mulder. (The second man in that office with Blevins and "The Third Man" is the "Cigarette Smoking Man".)
Later, throughout the series, he was then seen on a recurring basis as a character only identified as "Senior Agent #2".
So, since 'Fringe' hints that the "X Division" actually existed, why couldn't Camroux's character be one and the same in both shows? Couldn't it be pozz'ble, just pozz'ble, that Kenneth Taylor left the intelligence community and ran for election to the US Senate? (Probably with some covert help by his old buddies!)
I don't think the background of Senator Taylor is the kind of topic that will be delved into too deeply on 'Fringe', so we won't have to worry too much about this suggestion getting Zonked......
Now watch them do just that to thwart me!
