AU where Damian shows up two years after Bruce got back from the time stream and is half convinced Tim isn't real because there's no way a person can be THIS perfect.
The other Batkids play hot potato with him on weekends because Dick loves the kid but he WILL lose his mind if Damianās in his apartment for more than one weekend a month. He doesn't have the traumabond canon him has with Damian, so he's much more an older brother than anything parental.
Tim's AWARE of Damian, got a phone call to ask whether the kid could wear his old colors (Robin) and said yes, but he was barely listening & is based in another city and has been too busy to come for weekends home. He had no proper idea until two months later when he broke into Dick's apartment for a favor and he wasn't there and he finally decides to visit the Manor.
"What the fuck why's there a mini-Bruce here."
"Why do you know my NAME-"
Damian knew OF Tim, but was half convinced he was a myth because he'd never met him and Tim seems to have fought everyone and their international organization.
A sigh. "If Tim were here, he'd be able to to get us out of this. He's working on dismantling this trafficking ring."
"Grayson. We are in BOLIVIA."
Even after he met Tim, he's still half convinced he's an urban legend. Tim has the respect of RA'S and LADY SHIVA and is smarter than Batman yet still burnt his hand trying to make toast.
Tim's vaguely amused by Damian despite the murder attemptsāit helps that he doesn't live in the Manor and is nineteen now, with a good support systemāand accepts his weekends at the Tower or with YJ with grace.
Damian still snipes at him but Tim doesn't take much to heart. He's still irritated and snaps back sometimes, but it's definitely milder because "little brother or not, I refuse to have beef with a ten year old."
"Oh yeah, I see the Talia in you."
Kon's sort of concerned, but hey his little brother is indestructible and doesn't have that many friends, Damian could do with the socialization and Kon could do with some more time with Tim, so...
Tim drops by the Manor more and Bruce is glad, though he's too emotionally constipated to directly say so.
Bruce, happy to have his second-youngest at home more: You're. Back.
Tim, fluent in Bruceā¢ļø: Yeah I'll stay the weekend
Tim runs WE and Damian believes it's his birthright.
Damian also happens to be the only one that actually HELPS with WE, and at twelve ends up being better than their other siblings or even BRUCE at it, so Tim fully plans to hand it over to Damian as a twenty-first birthday present because it's not like the kid has friends or hopes and dreams or anything.
Tim actually has fought everyone and their mother btw. He got AROUND during his Robin and early Red Robin days, and still busts international smuggling rings for his own amusement. Sometimes he lets Damian help him when he's been nicer than usual
