In the beginning, Ezri was introduced as a young and confused woman who didn’t want to be put in the position she was in – to be a host to the Dax symbiont. I didn’t want to stay with that too long, and neither did the producers. If you had too much of her being confused, it would get boring.Nicole deBoer in Starlog, June 1999.
As time went on, you saw that Ezri was intelligent, that she was endearing and a good person. She became a more complicated character than you might have thought in her first few episodes. You saw a lot of surface stuff at the beginning, and then you got more into the character’s emotional makeup.
