As most of you already know, Denise Crosby (a.k.a. the actress that played Lt. Tasha Yar on TNG) created the character of Sela and convinced TPTB to incorporate Sela in TNG episodes. It seems to me that Denise Crosby could have also convinced TPTB to have Sela appear on DS9 as well, especially during the Dominion War episodes. Has anyone ever heard anything about this? Of course, you could say that Sela lost her standing in the Empire as a result of the snafu seen in Unification II
. Perhaps she was sent to jail (or executed) as a result of her failures in that episode.
