How would Renegade treat always-a-girl Robin Jason? The same? Better? Worse?
Renegade would definitely treat F!Jaybin a lot nicer, at least superficially.
I see many ways this could go.
Firstly, this version can be a lighter, enemies-to-lovers with cat-and-mouse, mainstream romantic take where Renegade finds it amusing to terrify Jay while she’s on the field, but he’ll never actually hurt her. In fact, if Jay is actually in danger, Dick will always save her faster than Bruce can blink. Romance and slow burn get-togeter yadda yadda
Then there’s the dark romance/dark erotica take which will follow pretty close to Renegade’s version, except the noncon will be softer and more in tone with the dark erotica flavor. Dick will be kind to her, praise her, and prioritize her pleasure… except she can’t say no and can’t leave. He won’t be as degrading as he would be with M!Jaybin as they wouldn’t butt heads as much. Dick will still be deeply damaged and believes he can’t love again after Kory, but F!Jay will be treated more as a prized, pampered pet than a toy to be abused and used. Dick will still be angry that Jay is on the Titans, and he will keep her in captivity and out of sight, but he won’t feel vengeful toward her. He simply… “enjoys” her company.
