I'm gonna get flamed like crazy for this, but I always hated this character and felt she is completely useless. I often times imagined in my mind how the series would have been without her, and truth be told, it wouldn't have been much different. Ed's childish nature also really toned down the serious edge the series had which made it so memorable for me in the first place. I understand she's supposed to be a comic relief character, but even in that regard she completely falls flat on her face. That's my opinion.
