Re: Romulan Liaison
Maybe T'Rul could've been an aide to Cretak.
That's actually a good idea and one the writers should have pursued. Aside from Cretak, we were treated to any number of "Romulan of the Week" characters who didn't stick around for more than an episode. Having Hackett return as T'Rul would have been a nice touch as it would have meant including a familiar character and also helped to bring the Dominion arc full circle by having her present for the end of the conflict that began, really, with her serving aboard the Defiant
four years earlier.
