The lack of female characters in Angel S5 was pretty glaring, and for that alone Harmony was needed. She was fun, great comic relief, but she also had a complexity that made her interesting. Of the two main female characters in S5, Harmony and Fred, Harmony is by far my favourite.

& Fred wasn't even Fred the whole season. She was Illyria so the writers adding someone we knew in Harmony was awesome
