I agree about Joran's portrayal. I think Brooks just used it as a reason to play nutso, and from the MU episodes he seems to really enjoy doing that. It did seem a little left field from the Joran we were introduced to in Equillibrium.
Though I thought the concept of the episode was cool, I didn't like the "I'm in love with you" twist at the end. I'm started to think that the writers/producers were certain that everyone who meets her must be head over heels in love with Jadzia.
