I don't think I made it clear enough why that's a retcon. The episode, at first, presented her as the villain, but it turned out kind of like Heroes form Batman Beyond, except she didn't go nuts at the end, and Superman had to sae her. It was a story of the government turning her into a weapon, and her desiring otherwise. And when she got what she wanted, it would make no sense for her to return, and become a baddie again. It's so nonsensical, that I consider it a retcon. (I also said "essentially", to hopefully clarify that they never went and said, "this didn't happen", but got about as close as you can.)
