no actually i have more thoughts on the idea of Jason and Damian role-switching regarding who stays at the league. in an au where Jason re-joins the family as Red Hood but Damian stays with the LOA for longer and Jason has to hide his secret overseas little brother, i do think it would be hysterical if, upon accidentally fucking up and revealing Damian's existence, Jason panicked and told Bruce Damian was HIS son.
just. Bruce thinking he's a grandfather. and Damian is his grandchild. he would flip shit.
Damian, who specifically decided to stay away from the Waynes because he wasn't ready to face his biological father after all these years being hidden, is so unimpressed with Jason. Jason is just biting his lip and refusing to make eye contact because listen he forgot who he was talking to and then panicked ok-
so the next time Damian visits Jason in Crime Alley and they accidentally run into the bats, Damian gets nervous about coming face to face with his father and just decides to go with the lie to save face.
Dick: oh my god i have a nephew
Damian, internally sighing: yes. hello, uncle nightwing.
Jason: *ducks out the conversation to silently wheeze*
the funniest thing about it, is that i bet once Bruce got over the shock of his 19 year old son having a 10 year old child (and oh my god Jason would have to bite his cheeks SO HARD during those awkward 'past trauma' conversations about statutory rape) he would absolutely ADORE being a grandad. he LOVES Damian. not only is this is his first grandchild but it's also a grandchild that is like. probably the closest he's ever had to a family member JUST as obsessed with the Batman and Robin mission as he is. like. Dick quit and fucked off to Bludhaven, Jason died and went crime lord, Tim's just weird, and then here comes his grandson, who is just as dedicated as he is and is willing to train for the mantle as hard as he remembers doing so as a teenager. he and Damian get along so well. and i just think it would be funny if like, after a while of Jason watching Bruce go all 'pops' on Damian and Damian just wide-eyed awkwardly not knowing how to respond, there would HAVE to be a conversation between Damian and Jason that was just like,
Jason: at this point i'm genuinely worried.
Damian, holding the supersized animal plush Bruce bought him at the carnival: it's fine he can afford it.
Jason: what- no. like, you know we can't keep this up forever. he's gonna need to know at some point that you're his son.
Damian, now also worried: why does that worry you?
Jason: it's just- you know, he really likes being a grandad! he's gonna be sad-
Damian, eyes widening pointedly: -you think that father will be SAD to know i'm his child? you think i'm going to disappoint him?
Damian, now panicking: YOU THINK HE WILL BE DISAPPOINTED THAT I'M HIS?!?!
Jason, immediately backtracking: are you joking? you're the kid Troy Bolton's dad wanted but never had,
Damian: who the fuck is troy bolton
Jason: he's gonna love you, he's just gonna be disappointed that he isn't a grandaddy anymore.
Damian: well i don't want kids, so he can suck it up.
*silence for a few seconds*
Damian: you know who will be devastated though?
Damian: 'uncle nightwing'
Jason: aw fuck he's gonna cry again isn't he-
