When Tuvok started serial killing Maquis in Repression... He had to select an order in which to kill the Maquis he killed didn't he? Janeway would have noticed if crew was being knocked off alphabetically, but since Vulcans are Vulcans, there must still have been a clearly logical pattern to his assasinations? Killing in order of height seems arbitary but what if he was killing the Maquis in an order of competency as reflected from 7 years worth of crew evaluations? Obviously since he didn't kill B'Elanna and Chakotay, the Vulcan machurian candidate must have been picking off the dead wood first.
