I think April gets a better showing in fanfic than the original GfU is because we don't have to maintain the conventions of a tv show, especially the need for the star to have the biggest screen time. That, I think, was their big problem. The star must have the biggest part (that's why Illya got captured and Napoleon rescues him) but they couldn't work out how to do that with April without letting her get hurt, or even potentially hurt.

By the way, has anyone used Randy (unfortunate choice of name in the UK) Kovacks in stories?
