Sexy Seska of Voyager

Star Trek: Voyager saw many a popular recurring character.  There's Lon Suder (Brad Dourif) the Betazoid who simply loved the thrill of the kill.  Naomi Wildman was daughter of Ensign Wildman - the first birth aboard the Federation Starship making its way home from the Delta Quadrant.  Of all the memorable supporting cast, Seska, played by actress Martha Hackett, delighted as one of the most devious and deadly of them all.

Hackett was no stranger to the Trek universe - having auditioned for the role of Jadzia Dax and losing out to Terry Farrell.  Before deceiving Voyager's crew as a Bajoran Maquis member who's really a Cardassian in disguise, Hackett played a Romulan in the Deep Space Nine episode, The Search. 

Though a popular character, Seska eventually met her end, but like the best sci-fi and Trek in particular, she managed to come back to cause trouble.  How many of us can say we complete unfinished business in our life - without actually doing it ourselves?  Through the miracle of holodeck tech, Seska returns to wreck havoc and target Tuvok - played by Tim Russ.
