I didn't forget Ezri; you'll note I listed "the obvious joined Trill" without specifying names. The issues Sisko has with Jadzia are later echoed - in a way - by the issues Worf has with Ezri. I see that as a second look at the same questions.

What I did forget was when Kira carries Miles & Keiko's baby and is both mother and not-mother to the child, not to mention wife and not-wife to Miles.
