The series' historic 100th episode "Timeless" goes back in history as Kim (Garrett Wang) and Chakotay (Robert Beltran) try to repair a past mistake (directed by and guest-starring TNG's LeVar Burton), and in another dizzying episode, "Relativity," Janeway (Kate Mulgrew) is spending her first day on Voyager when she discovers Seven, who has traveled back in time to prevent an act of sabotage. It was also a good season for buddies Kim and Paris (Robert Duncan MacNeill). In addition to "Timeless," Kim takes center stage in "The Disease" when he embarks on a dangerous romance. Paris is thrown in the brig in "Thirty Days," and his Captain Proton holodeck simulation goes haywire in "Bride of Chaotica!" In "Course Oblivion," a ship wedding is the prelude to a deadly displacement for the entire crew.

It wasn't all slam-bang action. The Doctor's (Robert Picardo) buried memories lead to an ethical conflict in "Latent Image," and he and Seven (the two most consistently interesting crew members) dabble in the most unlikely of romances in one of the series' most touching and memorable episodes "Someone to Watch Over Me." Also, Jason Alexander (then in Seinfeld) guest-stars as a scheming alien in "Think Tank." Voyager didn't always close its season with a cliffhanger, but in "Equinox, Part 1" an attempt to aid another Federation starship in the Delta Quadrant uncovers a threat that might destroy them both. --David Horiuchi
