Okay so I know evil aus are annoying but au where Leafpool isn’t necessarily evil, but manipulative.
Jayfeather isn’t born blind in this au. Leafpool, fearing that none of her kits would be medicine cats, and in turn not be close to her, blinds Jaykit herself. She blames it on a rabbit attack when Squirrelflight asks.
Things go on as they do in cannon, Jayfeather trains under Leafpool’s apprenticeship. But he starts to notice that whenever he mansions hating being blind, she seems to feel guilty, but he’s unable to figure out why.
When the three are figuring out who their biological parents are, and Jayfeather recalls memories from his birth, remembering Leafpool as his birth mother and the “rabbit” attack. He realizes he has memories of sight and comes to the conclusion that he wasn’t born blind and instead made.
