I want to give another moment that was a favorite and made me convinced Ezri was a worthy replacement to Jadzia. It was her scene with Worf in Tacking into the Wind where she rightfully criticizes Klingon History sending Worf over the edge. Considering Curzon and Jadzia were very much engrained in Klingon society, to have Ezri come out and say that was very bold and one of my many favorite scenes in the episode.
I thought this was an excellent scene as well. One that really showed the difference in Jadzia vs. Ezri. This is when I started liking her.
