Easily one of the best, without a doubt. Seeing her development is great.
At one point, to somewhat paraphrase, there's a moment where you get to ask her something like, "What about *your* wants and needs, Lae'zel?"
To which she replies something along the lines of: "(doing this thing to help someone else) ...is my want and need."
The depth of her character is great. She is, in her way, inspiring. And she is arguably the best of us. I don't regret having her in my party, not for a second.
