A/B/O verse where part of Bruce’s issues with Robin Jason is that he presents as an Omega and Bruce thinks it’s making him too emotional. They still blow up, Jason runs away, gets murdered, gets brought back to life, and when Talia finds him she chemically transitions him to an Alpha. She cannot protect him 24/7 and for all that the Alphas in the LoA are loyal, they will still see a catatonic Omega as easy prey.
When Jason comes out of the Pit a large part of his rage and anger is driven by the forced change. His mind and body at war with each other. It takes Bruce longer to figure out The Red Hood’s identity because of the difference in designation. He doesn’t figure it out until he’s face to face with Jason, the Joker, and a gun.
It takes years but Bruce does make an effort to reintegrate Jason to the Batpack. He’s helped in large part by Dick. Until the day finally comes that Dick is able to coax Jason into the pack nest and Jason has a full breakdown. He missed this, but it still feels wrong. Being an Alpha sucks so bad, but even though he’s tried to reverse the transition it’s never stuck. He went into the Pit as an Alpha so he came out as an Alpha for good.
Bruce comes to check on them because he hears the crying. While Jason sobs about how everything smells shitty and he can’t recapture the feeling of being safe in a nest he built, Bruce starts formulating a plan. Chemical transition is the modern equivalent of a very old, very archaic practice. If Jason can’t chemically transition there’s still a way to make him an Omega. He checks with Dick first, as the other Alpha in the pack he’ll need Dick’s help. At first Dick is apprehensive, but agrees to at least bring the idea to Jason to see what he says. Bruce dedicates himself to formulating a proposal for Jason.
Jason is absolutely not expecting that the next time he acquiesces to spend the night at the manor, Bruce and Dick sit him down in Bruce’s study and present him with a 20 step plan to bitch him. Steps 10-20 largely consist of Jason being fucked in turns, simultaneously, and continuously by Bruce and Dick. There’s a detailed timeline, a plan for a custom breeding bench, his own hormone levels mapped, a proposed list of approved sex toys, four different collar designs, a consent contract in triplicate with each of their names on it, the paperwork to legally revive the Wayne Omega: Jason Peter Todd Wayne as either the son of Bruce Wayne, or the mate of Dick Grayson, or the mate of Bruce Wayne. It’s an overwhelming amount of information and Jason feels dizzy with it. Bruce talks through it in a totally clinical way. Dick looks slightly pained standing at his side.
Jason wants to cry. They cared enough to plan this but obviously neither one wants to do this. It’s a good plan though, technically any Alpha could do it. Hell Jason could just find a few thugs to fuck him until he’s an Omega again, he could’ve just done that ages ago and saved Bruce and Dick the trouble. When he tells them as much Bruce growls so loudly Dami pokes his head in to ask if everything is okay. Dick hustles Dami out of the room and locks the door behind the boy. Jason isn’t sure why they both smell so angry and it’s making his own stupid Alpha brain anxious as hell. Finally Bruce regains control and tells Jason that under absolutely no circumstances will Jason be bitched by anyone but them. Jason wants to scream that Bruce can’t tell him what to do, wants to storm out just on principle. It’s Dick’s hand on his shoulder that stops him. Dick that settles his other hand on the scruff of Jason’s neck and explains that they wouldn’t trust anyone else with him. That it will not be a painless process, that even if Jason wants it, his body may try to fight them, that they’ll have to tie Jason down and fuck him through him begging them to stop, that neither one of them want to hurt Jason like that, but they will if Jason only asks for it.
Jason doesn’t ask, he begs.
