alternatively, could we have an au where Jason has to be the one that delivers Damian to the manor in Gotham, and he gets so distracted with trying to make Damian's first trip outside the league enjoyable (road trip, theme parks, bunch of stop-offs along the way) that he completely forgets to set up his own place to stay in for after Damian's gone to the manor. and the two end up in front of the Wayne Manor driveway in the middle of the night arguing about it like
Damian: it's just a night or two, and it's not like Father doesn't have spare bedrooms available. Jason: that's not the issue, the issue is that i don't want them to fucking know i'm here. Damian: ok so i'll distract them and you can sneak in the back entrance. Jason, flatly: you want me to sneak into my old house to spend the night, when everybody thinks i'm dead and i want it to stay that way? Damian: i'm just saying that his long lost blood son showing up is a good distraction, and it IS a big manor. i'll bet you anything that i could keep you hidden in there for as long as you needed. Jason: you fucking could not. Damian: i could. Jason: could not. Damian: i could and i'll bet fifty dollars on it. Jason: Jason: Jason: alright.
Damian ends up keeping Jason hidden in Bruce's own house like a kid trying to hide a puppy they found on the street in the back of their closet. he's sneaking Jason food and building him a little hidey-hole in the attic above his bedroom and literally nobody else in the manor has a single fucking clue. Jason already knows all the hidey-holes and secret passages from when he lived there anyway, so it turns out not to be as hard as he thought.
to be clear, he still becomes the Red Hood. he's not spending every second in the manor; he's sneaking in and out on a daily basis while he sets up a rulership in Crime Alley. it gets to the point where he fully has his own apartment that he could move into at any point, but he and Damian are being so stubborn about this bet that he's just staying at the manor anyway to prove that eventually they'll figure it out. plus it's starting to get really fucking funny because he's started playing ominous ghost sounds in the ceiling above Tim's room and the poor guy fully thinks he's being haunted by his predecessor's ghost. a fact which is almost correct.
the only thing that's frustrating the hell out of Jason is the fact that after every single interaction with the bats, no matter how exhausted he is from working all night, he has to watch Bruce drive the others right back home while he waits and then has to walk back by himself. eventually there's an arkham breakout and it's so bad that the bats are readily accepting Hood's help with dealing with it and it takes so fucking long to sort everything out that when it's finally over and they're ready to 'go their separate ways', Jason is so genuinely dead on his feet/in pain and need of sleep that he stops caring about everything. Bruce tells the bats to get in the batmobile and Jason just trudges over and slides in next to Tim.
everybody freezes and. straight does not know how to respond. Jason's just half-asleep already leaning his head against the window, and Bruce eventually has to clear his throat and ask like "...would you like a ride home, Hood?" and Jason just grunts.
"where do you live?"
"Wayne Manor," Jason mumbles, barely conscious. the bats all bluescreen apart from Damian who is so resigned to his big brother's idiocy at this point that he just tells them to take him back to the cave with them.
"just- just bring him. look at him. what trouble is he going to cause? he's tired, Father. let him rest."
Bruce is... so confused. and so concerned. but if Hood's injured then what harm is there in letting him get checked over and sleep the worst off in the batcave medical suite? he did help out a lot that night, after all. except when they get to the cave Bruce and Dick start preparing to carry the asleep Red Hood onto a medical bed when Damian just kicks him in the ribs and says 'we're home', and they watch in baffled fucking silence as Hood wakes up, blearily blinks while he takes in his surroundings, and then gets up to start trudging straight up and into the manor.
the others can do nothing but watch in quiet disbelief as Hood proceeds to go through the manor like he truly knows it, gets to Damian's bedroom, and then sleepily climbs up through a secret passage in the ceiling that, when Bruce pokes his head into, reveals a fully renovated bedroom filled with the Red Hood's gear and personal possessions. Hood flops down onto the bed and passes out immediately. Damian just bids Hood a good night and calmly closes the opening behind him, before turning to face the incredulous faces of his entire family staring at him like he's a fucking alien. he narrows his eyes.
"we will talk about it. tomorrow."
"Damian-"
"we are all tired." Damian determines. "for now, let him sleep."
"IN OUR HOUSE-"
"WE WILL DISCUSS THIS TOMORROW."
the next morning Jason wakes up at like. noon. and remembers the night before. and he crawls down into Damian's room to nudge him awake and firmly tell him 'i am not giving you fifty dollars'.
the ensuing argument wakes up the rest of the family.
