Headcanon that Jason just kidnaps his siblings instead of asking them to hang out sometimes.
Sometimes he does the normal abduction thing and other times he has his methods.
Dick: Jason sneaks into Dick’s apartment in Blüdhaven at 3 AM, throws him over his shoulder, and drags him to his motorcycle. Dick wakes up mid-ride, half-conscious, groggily mumbling, "Jay, what the hell—?"
- Jason just shushes him and tosses a burger into his lap. "Shut up and eat, Goldie. We're bonding." (Jason, allowing his big brother to ruffle his hair? Nooooo, absolutely not...)
Tim: Jason straight-up drugs him asleep him when Tim refuses to take a break. He wakes up in Jason’s apartment with a cup of coffee and a sandwich waiting for him, while Jason sits on the couch reading a book.
- “You looked dead on your feet, Replacement. Either you napped willingly or I made you. Guess which one you picked.” (Jason totally doesn't rake a hand over his lil bro's hair during this time)
Steph: Jason knows Steph is a wild card when it comes to hanging out, so he has to be a little sneakier with her. He'd show up at her place unannounced, pretending to just be casually passing by, and in one smooth motion, he'd grab her and yank his little sister into his car or bike before she even realizes what's happening. (He totally doesn't do this in time with hard school, noooo)
Damian: Jason scoops him up mid-battle and just walks away with him. Damian kicks, bites, and yells, "UNHAND ME, TODD!" but Jason holds him like an angry kitten.
- They end up at a rooftop picnic with Alfred’s homemade food. Damian eventually eats while grumbling about Jason's “barbaric methods” but secretly enjoys the attention. (Jason maaayybe ruffles his hair a lot.)
Cass: She just lets it happen. Jason shows up, gestures toward his bike, and Cass just hops on without a word. They go on long road trips in comfortable silence, getting ice cream at 2 AM and scaring off criminals for fun. (Jason totally doesn't take the time to help her with her speech-)
Duke: Duke gets fake-napped. Jason tells him, "Be outside in five minutes," and when Duke says no, Jason still shows up, grabs him, and hauls him into a car.
- Duke just sighs and texts Bruce: "Jason's 'kidnapping' me again. Back later." (Jason totally doesn't get the names of school bullies from him and uses them, noooooooo)
Bruce knows this happens. He just sighs and lets it happen because, honestly? It’s Jason’s way of showing love. And at least the kids are getting along.
Jason kidnaps his siblings because it's his way of saying, "You're important to me, and I'm gonna drag you into ridiculous situations whether you like it or not."
He also, however, does it to Bruce.
In fact, it might be one of his favorite things to do, just because Bruce is always so serious and “responsible.”
Jason thinks it’s hilarious to force Bruce to take a break. He just shows up at the Batcave, probably with some kind of overly complicated plan to "kidnap" Bruce without him realizing.
Step 1: Jason would distract Alfred with a "Oh, just a quick check-in, you know, 'cause it’s been a while.’"
Step 2: He would wait for Bruce to get fully immersed in some case files and then sneak up behind him, tap him on the shoulder, and when Bruce turns around, Jason’s already got him in a headlock, pulling him out of the chair like, "Get up, old man. We're going to a diner. No arguments."
Bruce would protest, of course. He'd probably try to get out of it with his usual grumpy “I’m too busy” routine. Jason might fake-sigh and act like he's just trying to help Bruce loosen up, reminding him, "I know you think you’re invincible, but you still need to eat, Batman."
And if Bruce insists on not going, Jason would just drag him anyway. He might even grab the Batmobile for a joyride (he's always wanted to), making Bruce sit shotgun while Jason drives like an absolute maniac (Jokes on both because Bruce taught him to drive-)
Bruce would probably be scowling the whole time, but Jason would know his dad is secretly enjoying it, even if he won't admit it.
Eventually, Bruce would probably give in and get his grumpy little “dad” lecture—“You’re so reckless, Jason—” but Jason would just smile and be like, "Whatever. You’re welcome.”
Jason totally doesn't like it when his dad just ruffles his hair at some point.
