1) Ezri undergoes the zhian'tara (cf. Facets) and Jadzia's persona enters Worf. They missed some great, tender moments.
2) Ezri undergoes the zhian'tara and Jadzia's persona enters Quark. :-)
3) Troi shows up while Worf and Dax are still courting which makes Worf uncomfortable but not as much as Dax and Troi getting along so well.
Not having the Enterprise-E in the war the least for one episode was a missed opportunity.
Ezri fully maturing...
I liked the way she was portrayed in the last
nine episodes.
