I had two Derp Ends in mind, and settled on the Princess Fionna one. However, I liked the other one too much to discard, so I made it into another ending: the Epic End. (in all honesty, I hate that word for the most part, but it fit too well here)
This wasn't planned, but in a way, since the original "Good Realistic" idea was ditched, the Good End could take that role and this could take the "Good Unrealistic" title.
