Here's something I've been wondering about. I thought that the joined Trills were't supposed to reassociate with their past: isn't that what the episode with the woman-to-woman kiss was about? So how can Dax (Ezri) come back to DS9 as a joined Trill? Was this explained in the series? If so, I missed it. I just finished rereading "The left hand of destiny" (which is fantastic, by the way) and started wondering about that.
