Risa

Gotta say though, I wouldn't mind the unceremonious death of Jadzia if it wasn't wrapped up in the sexist contract disputes, because the character is the perfect one to kill off, because she was (in a sense) only mostly dead! Imagine if we had gotten the chance to see Ezri talk to Jadzia, like we saw Jadzia talk to former hosts.

The two of them could work through the complications of living on the same station as Jadzia's husband, how her death wasn't some honorable warrior's death like Jadzia (and Curzon) would have dreamed about, and how Ezria wasn't ready for the responsibility of being a host. There's a lot of really interesting stuff writers could play with there, and I think Adira and Gray in Discovery have showed there's some nice storytelling potential there (the same kind of additions to canon could have happened with Ezri and Jadzia, in terms of a traumatic host transfer causing unexpected bonds between the hosts' memories).
