Sorry, my brain's a mess after reading this, so I can only describe it in one word: wow.

One thing I loved that you did is that you ended Butch's and Buttercup's childhood rivalry with an explanation centered on age and natural maturity. I've always wondered if, and when, The Powerpuff Girls would call it quits to live their lives.

They're normal girls, within themselves, minus those powers. They'll grow to want their own lives and families and to have personal aspirations. After all, they're FEMALE. They'll... want more and more as they mature a man's affection and, perhaps more than anything, a child of their own to nurse.
