Absolutely. Okay so hear me out.
Riddler gets absolutely obsessed with this, cause how could you not, right?!?
Bats freaks out as you do because Riddler apparently knows all of their secret identities now even if according to him “that’s not important right now.”
Batman calls Superman to check the grave too, and once he verified it’s empty, they dig it up and Bruce goes over the evidence to determine what happened (Jason dug himself out and that’s a whole other traumatic reveal he’ll deal with later)
It takes a minute to get an idea of what happened, but Bruce discovers that the League might be involved, so to Nanda Parbat they go, they being batman, nightwing, Superman, Wonder Woman (who found out somehow and Bruce is too busy to even look into that [it was Clark]) and riddler who WILL be seeing this through, thank you very much. Honestly Batman can’t find it in himself to care so why not. Riddler is coming with.
Bruce: I’m here for my son.
Someone else, Ra’s or Talia or whoever: How’d you find out about Damian?
So apparently he’s here for two sons. Dick gives him a look of absolute judgment but he can deal with that later. Or never. That works too.
Riddler makes himself surprisingly useful by proceeding to annoy the ever-living shit out of Ra’s.
Maybe Batman can convince riddler to stop being a villain because everyone honestly he would love to see more of this. But no time right now, they have to find his son. Sons. That’s going to take a minute to get used to.
So they’re working their way though and Ra’s doesn’t seem to be trying too hard to stop them (because honestly if they take that absolute menace of a zombie kid away from here HE’S not going to be the one to complain, and it’s not like Talia could even blame him in that case)
So anyway batman and co are going through the (very large) place and eventually they barge into some room and Jason’s in there just chilling. Maybe eating cereal or something. Sweatpants or something like that. Just, not what any of them would have expected.
Jason takes one look at Batman and yells out “TALIA,” who appears right on cue.
Riddler, popping in from the background: I figured it out!
Riddler: you said to check your grave
Talia: great. Now that that’s all settled, go pack. You’re going back to Gotham.
Jason: wait no, what about-
Talia, putting him on the cheek: I’ll take care of it sweetie.
Talia then leads all of them to Damian and introduces Damian to his father.
Damian: I thought you’d be taller.
Dick: Yep. Definitely your kid.
Talia makes them sit down for dinner all together and tells them they can go back in the morning.
Honestly Bruce isn’t going to fuss about that right now because he has SO many questions for Talia but Jason’s alive and he has another kid too that apparently Talia didn’t feel like telling him about, and Jason has possibly spent the last hour glaring at him but he’s alive, so they can work whatever this is out
Meanwhile Talia takes a quick jaunt over to Gotham and decapitates a clown.
Batman and co head back to Gotham the next day, Jason (reluctantly) and Damian (skeptically) in tow, only to find out immediately on arrival that the joker is dead.
Jason immediately stops glaring and Talia is suspiciously waiting for them at the manor.
She and Alfred both raise an eyebrow in Bruce’s direction as if daring him to say anything.
Tim shows up because he’s here to find out what happened/if everyone is okay, and sees Jason. Jason starts glaring again as Dick introduces the two of them. Tim’s eyes go wide and he’s so excited and all of a sudden Jason is faced with a very excited, very talkative kid that’s like four feet tall and dang it, now he can’t hate the kid.
Damian does not approve of the attention Jason is giving Tim. Jason does stop Damian from stabbing Tim though.
At some point though Tim asks why the riddler is there too.
Riddler is here to stay now. There is no getting rid of him. When Steph shows up riddler announces that he will be coparenting her with Batman and Steph is just like lol nope
Bruce can tolerate Riddler’s continued presence in their lives because (a) it means he’s too busy to do crime and villainy stuff and (b) he sends daily riddles to Ra’s and manages to annoy him from a distance and honestly that’s a wonderful thing for Batman to sponsor
That’s it. That’s all I’ve got.
