Re: TNG "The Defector" plot thread continued in DS9 "The Search"
Plus, T’Rul was played by played by Martha Hackett, who also played Seska on ST:Voyager. She’s a good actress. Of course, that would have meant that she would have been playing regular reoccurring roles on 2 different Star Trek shows at the same time.
Which may well have been a factor with why nothing was done with T'Rul. Since DS9 and Voyager were filming at the same time, it could have been quite difficult trying to accomdate the same actress with recurring roles on both shows. Seska was the one they had story material for, therefore that's the character they chose to develop.
