Cy would be wayyy less reluctant and "no homo" to get with Eden in a CF AU, although he'd still call it an exception, and they'd make things official way earlier. Overall, less homophobia, but Eden might be more of a narcissist and generally unchecked asshole. Just two dumb bitches telling each other "exactlyyyy".

CF AU TheaLynn would have Thea coming to terms with being a lesbian as well as realizing she likes Lynn wayyyyy earlier than in yuri canon, but in turn, Lynn would friendzone her (just bestiiies!) for a while and wouldn't consider dating Thea until after The Incident and having her help with the recovery. Slower burn but at least Thea is probably more emotionally balanced and generally more self-confident for it, while Lynn is like, insanely spoiled. The most pillow princess to have ever princessed
