I keep turning this concept in my head but I can't manage to write it satisfactorily so here I am, setting it out in the wild:
Tim Drake being alerted that Batman INC is something that is in the planning stages of it happening (maybe by Lucius, maybe by Tam, who even knows, look he was CEO for a while and someone is worried about Bruce Wayne about to go public with Batman INC and they get in touch with him) and going to Bruce and refusing to let him do this.
Because Bruce is needed in Gotham and Batman is needed in Gotham, and while Dick is doing a great job and no one will convince Tim of the contrary, that's not Dick's job. It's Bruce's.
(Who also has a son who just got his father back and if anyone knows what it would mean for a son who lost their father to get that father back when you know it's not going to happen... well lets say Tim has Opinions about this [and while he might not get along with Damian all that well yet, they are in that neutral state where Damian is like a cat observing things and studying dynamics and Tim has always been able to work with people he doesn't like or even trust much, so he's not going to punish the kid over whatever's went down between them.])
And besides, let's be real here Bruce, if you want a Batman that can go around the world and pull together teams and make them cohesive and knows what it's needed to be a successful team of young / upcoming young heroes, that's way more Dick than you yourself. Would be preferrable if he was allowed to do it as Nightwing, but the point still stands.
Just ... Tim pow-wowing with Bruce over the whole sitch and convicing him to back down. Not abandon the project, Tim knows that will not happen no matter what Tim does, but trusting it to Dick, who is way better with both younger people and people skills in general than Bruce.
(Which actually is not meant to separate Damian from Dick, Dick can come in from one assignment to the next and check on Damian and this is not the time it was when Tim was growing up, they have communications all over the globe now, Dick can phonecall and videocall Damian as many times as he wants and check on him as often as he wishes, but if Batman INC is happening, and it will happen because Bruce has decided it will, then Tim can only do damage control over this)
And possibly Bruce leveraging Tim staying in Gotham (which, joke's on Bruce, Tim was going to do that anyway, but sure he'll "concede") and possibly "asking" (ordering, let's be real here) Tim to help train Damian (which Tim isn't enthusiastic about but fine, he'll make it work as long as Bruce has his back), for multiple reasons.
A bit because Bruce sort of feels guilty that Tim was kicked out of the Robin role (Bruce HAD promised it would be Tim's until Tim decided otherwise, [which I don't think Dick knew about and even if he had, the situation still had been what it was, to be fair to Dick]) but also Bruce doesn't quite know what to do with Damian (and it wouldn't be the first time he's trusted Tim to teach young heroes / guide someone in a vigilante role) and also he both wants Tim to be there with him (he's missed him) and needs him there with himself (Tim the emotional regulation parentified wonder!).
And then shenanigans from there.
