So let's imagine a DS9 sequel series or TV movie is green lit and you're the producer. Does Jadzia come back? If so how? Or does Terry Farrell come back in some other way? Or is she not in it at all?
Aside from flashbacks or time travel, there’s always having Ezri do some sort of meditation/dream sequence/other Trill something-or-other wherein she encounters previous hosts, one being Jadzia. That’s happened a few times on DS9.
Oh yay! Happy birthday to a wonderful actress! It is mine too, and I'm going use this as some kind of brag, or at least a new way to wedge Star Trek into a conversation.
