"Riddles" (VOY)
Tuvok and Neelix have been the obvious odd couple on the ship since Neelix first tried to hug "Mister Vulcan" in the pilot episode. "Riddles" may be the strongest and most touching episode in the Tuvok-Neelix arc. Here the true depth of their friendship is established. Really, it is probably this episode which carries the emotional weight of Tuvok's "dance" for Neelix when he departs at the end of the next season. The premise is an attack by a shadowy (pun intended) race called the Ba'neth leaves Tuvok in a coma. He wakes up mute, disoriented, and with a severe brain injury that leaves him in an child-like state. To obtain information on the weapon, Janeway teams up with an alien investigator to track down Tuvok's assailant. That plot in itself is fairly standard, and it's not the only time the Doctor has claimed he needs more information about a weapon to undue the damage that it has caused. That seems like a stretch - something like sayin...
