I think she had some interesting developments in all her original series appearances, they naturally built on each other as they went along. Development stopped when she was brought into Alien Force, but yeah, "Where the Magic Happens" finally did something with her, and something really cool too...and then the morons in charge did TWO episodes, right in a row even, that screwed it over.

I really cared for the character, so such disregard for her and her fans on the writers' parts pisses me off.
