I have no idea if you meant this as a prompt or not, but headcanon accepted. Thank you @yeats-nana for looking this over
Okay, so he got a headstart with Dick’s friends, which is only natural, seeing how some of them were on his team for a while.
(“Always will be, Jaybird,” Roy says, and Jason only rolls his eyes a little.)
No one actually likes staying at the manor, so it made sense that they crash in his safehouse-warehouse-apartment-club thingie instead. It gets bad enough that he grudgingly converts three rooms into guest rooms and doubles up on his groceries, just in case.
He picks up Bart by accident. Something blurs past him, and he reaches out by habit, grabbing whoever it was by the arm and stopping them in their tracks. It’s a neat trick, even if it always makes him feel like his arm socket is getting chewed on by Krypto.
Honestly, he expected Wally. But that’s a significantly less amount of human dangling from his hand. “The fuck?”
Oh, he’s seen that particular combo of bad boy looks and himbo vibes before. “You’re Drake’s clone boy, aren’t you?”
“He totally is,” the speedster still in his grasp—Bart—agrees equitably. “Hey, you’re Jason, right? Is that pizza you’re carrying? Can we come with and have some? Because I’m starving.”
Jason’s so flabbergasted that they know who he is and don’t immediately, like, try to kill him for what he did to the replacement (which—fair) that he completely forgets to object when they invite themselves in. And then call someone called Cassie to come over, but not bat-Cassie, which just makes things needlessly confusing.
Apparently, once the kids decide you’re the ‘cool brother’ (and Jason will never let Dick forget that), they never leave. Whenever it’s field-trip-to-Gotham time, or whatever they do when they’re here, they stay at his place. As a consequence, he sees a lot more of replacement—Tim, these days. The kid seems to think it’s the funniest thing that ever happened to him.
It’s not bad. It’s not bad, at all.
(He could do without being asked for relationship advice by teenagers deep in the throes of puberty, though.)
Steph tags along one day and just never leaves. Jason has no idea what her deal is, but he likes having her around and is more than happy to have her study in his living room. At least someone in this family is taking education seriously.
And Jason thinks that’s it. It’s more than enough, honestly. Everyone is pretty good about leaving him be when he actually needs some privacy; it’s still a lot.
Until he finds a miserable looking Superboy, Version Two, curled up on a roof.
Jason takes a second to put his guns away and double-check his hands for blood. Then he approaches cautiously. “Hey, Jon, right?”
The boy startles. For a second, his eyes glow red before he visibly calms himself down. “Oh, hey, you’re Robin’s brother! “
Jason tries not to sigh. “Yeah, I guess. What’re you doing here?”
“I wanted to meet up with Dames, but he’s not back yet.”
It takes a moment for Jason to connect ‘Dames’ with the Robin who tried to stab him two days ago, and not in a playful way.
“You could wait for him at the manor,” he suggested.
Jon looks down. “I might fall asleep.
“I don’t think that’s a good idea.”
“Uh.” The kid shuffles awkwardly in place. “Sometimes I get bad dreams, and when I wake up I don’t—”
“How about you stay over at my place?” Jason hears himself ask. “The rooms are Roy Harper-proof, you should be fine.”
Wide blue eyes stare at him in confusion.
“It means they can withstand anything you can throw at them.”
“Yeah, your brother stays over all the time, he tried to break them before. You can text him if you want to.”
But Jon perks up. “Oh, if Kon stays there, it should be fine! Thank you!”
(Jason plans to have a talk with Jon about that in the morning. Really, he gets that the kid is superpowered and doesn’t have to fear much, but you should not go home with a stranger! What if Jason was more of a villain?)
By the time Jason gets them home and shows Jon his room for the night, the kid is already half-asleep. Man, was he ever that young?
“Dames might stop by later,” he tells Jason, just before falling face-first into bed. His next words are distorted by the pillow, but still audible. “It’s okay when he’s there, you know. It never gets bad then.”
Christ. “Okay. Good night.”
He texts Dick to let him know what happened, and as soon as he gets the number from his, Lois. Because Superman is off-planet right now, but he is not the terrifying one in that marriage.
(Little does he know it’s the beginning of a beautiful friendship. Lois is not one to let contacts with knowledge about organized crime go to waste.)
So really, this is it. Roy and Kori drop by frequently, Tim’s gang less so, and Jon likes to drag Damian along for visits. Steph has started paying rent. (Jason doesn’t have the heart to tell her he’s his own landlord because the old one was exploiting minors and had to be dealt with.) He’s cooking for three or more people most weekends, which is as he likes it.
And then, one sunny afternoon, the doorbell rings.
Jason frowns, because—no one really does that anymore. So he’s cautious all the way down the stairs, opening the door in person, just to find a slightly awkward looking Duke Thomas standing there, clutching a backpack.
Duke draws himself up. “Stephanie said you’re good at tutoring and I—I might need some help. To keep my grades up.”
And fuck, it’s not like Jason can say no to that. As far as he knows, Duke is a straight-A student.
He steps to the side and lets his brother inside. “C’mon in, then. I was just preparing lunch. Hope you like alambres.”
