Plot devices or not, I hope we keep Odo home in the Alpha Quadrant and is reunited with Kira. I miss them as a couple, and they're parting in What You Leave Behind
was so heart wrenching yet classy and well done. Give me Odo and Kira over anymore of the Kassidy/Benjamin angst anyday.
Yet sadly we'll probably get more Bashir/Ezri/Whatshername drama like we did in Zero Sum Game.
