Tim takes a prank too far. This is, of course, relatively normal for him to not know when it is normal to stop playing along.
Damian makes yet another quip about Tim not being good enough or whatever, Tim doesn't really know he wasn't really paying attention, and Tim.
Tim has an epiphany.
A long time ago, back when Young Justice was still relatively new and getting neck-deep in intergalactic and interdimensional trouble, he'd made a friend.
That friend is a little difficult to get ahold of, and he hates the method he has to use to do so, so he doesn't usually reach out.
But he really, really wants to fuck with Damian.
He brings out the mangled, horrible amalgamation of old tech, future tech, and fantasy tech that creates a block that could vaguely be a cell phone (this horrid thing is the bane of his existence and he hates it so fucking much), and makes the call.
"Hey is there anyway you could pretend to kidnap me after a long, boring monologue broadcasted across Gotham? I really need you to state that the reason you're 'getting me out of the way' is because I was the best Robin. No, I'm not Robin anymore. No, I'm...I'm Red Robin now. Stop laughing. What do you mean restaurant chain?! Danny. Danny. Come on, lemme take a week long vacation in the Realms. Please? Sweet, see you soon, just gotta let me pack real quick."
That night, as Red Robin is out on patrol, the sky turns into a sickly green. Purple fog rolls in, disjointed whispers giggle and gossip from mouths unseen, and every single screen in the city of Gotham is forcibly turned on to broadcast the speech of a white haired, fae-looking villain.
He wears a black and white jumpsuit, a Green Lantern Ring that keeps glitching out the camera focus around it, and a crown of ice that moves like fire.
He give a grand speech about how he's going to get back at Robin, for foiling his plans. That Robin was better than his any other who has ever borne the name, and he wanted it to be known to the world that this was an honorable battle he'd had to struggle with. That, regardless of losing the first time, in order to ensure the success of his plans this time he's going to take Robin out of the picture early.
The Bats get prepared to defend Damian with their life, Damian who is strangely flattered; only for the villain to hold up a seemingly unconscious Red Robin and dramatically disappear into a green portal.
The sky goes back to normal, and the fog and whispers go away.
Damian is pissed. Then worried. Then both.
He will rescue the fool and prove he is superior.
Meanwhile, Danny and Tim are catching up and vibing as Danny puts the Ring of Rage and Crown of Fire back in their special places. He doesn't need them or anything, they just had that 'villain' vibe he'd needed.
This absolutely means the rest of the team will call Danny for a holiday kidnapping. Excuse them! How dare! WE DESERVE holidays TOO! No, You get your ass over here pronto! Time for a road trip babes!! Woohoo!
Batfam and Justice League? Gearing up for war. The King of where just kidnapped their side kicks?!?!?! JLD call shenanigans. King Phantom doesn't do this shit. He just doesn't. But also, if this is a weird prank? They do NOT want to be on the wrong end of ruining it soo...
Superman was just on his way to get Kon (because he needs info on Young Justice Shenanigans, he saw the broadcast and Bruce hasn't asked yet, but it's better to be ahead of the game) when Danny opened a much more subtle portal to "kidnap" him.
Superman stares at Danny.
Danny stares at Superman.
Kon holds a finger to his lips and shushes Superman.
Danny and Kon slowly slip into the portal.
Clark knows Kon is okay and is absolutely going in out of his own power. He also knows this means that it's probably some sort of weird prank.
Now he's torn.
Does he betray Tim, who has more blackmail on him that Bruce, by telling everyone that it was just a prank? Or does he betray Bruce, who has less blackmail but knows him on a more personal level, by not telling him that it's just a prank. That it's just a bunch of stupid kids getting together to hang out.
He decides...to use Lois.
"Can y'all babysit Jon? For like...how long are you going to be gone?" He rushes out before the portal can close.
"....A week?" The white haired teen ventures, shrugging.
"Yeah, a week. Can you babysit Jon for a week?"
Kon brightens and opens his mouth, only for the 'villain' to slap a hand over it.
"How much are you willing to pay?" Kon's friend asks, eyes narrowed.
Clark uses superspeed to rush back to his clothes and grab his wallet. And Jon. And Jon's things.
Jon is far too bemused to put up a fight as he's tossed like a bag of potatoes over Clark's shoulder.
"I've got twenty bucks in cash, a coupon for a free pizza, and uh...twwwwo? Favors?"
Kon slips the hand away from his mouth.
"Three favors."
"Twenty bucks, a coupon for free pizza, and three favors."
"Done. Jon, you get to play with real life pirates that won't break when you punch them."
Jon leaps off of Clark's shoulder and barrels into Kon and Kon's friend. The portal closes behind them, cutting off Jon's excited chattering.
Clark takes out his phone and shoots a text to Lois, asking if she wouldn't mind a second week-long honeymoon, that he's already arranged for a week-long babysitter for Jon, before texting Bruce and telling him that on Lois' order he'll be unreachable for a week.
He's not getting involved in this.
