Okay, but listen, I’ve been thinking about this and I’m pretty sure that only a small part of the Justice League knows that Bruce is Batman and obviously, most of the rogues gallery is in the dark as well–but Selina is another story. Like, she has a record, compared to Bruce LOTS more people KNOW she’s Catwoman.
So basically, if she agrees to marry Bruce, any romantic relationship she has with Batman is out the window when they’re out and about. Like, strictly professional when they’re around other people.
I can see the hilarity that would come out of it.
Like, imagine 99% of the Rogues gallery tracking him down after “The Future Mrs. Wayne?” gets slapped all across the tabloids. And at first, Bruce is like, shit…wtf? Because night after night he’s got Harvey and Jervis and Fries hunting him down.
But instead of trying to kill him they’re all, “We’re really sorry about this whole Bruce Wayne thing. We were really rooting for you and Selina.”
The only ones that don’t come to congratulate him are Ivy and Harley (and possibly Eddie since last I checked he DID know Bruce’s identity), because they’re busy tracking Selina down and being all, “Well, good for you. You finally ditched the Bat. He was never any good for you anyways.”
(She laughs so hard when she finally gets away from them, she can barely breathe, let alone talk, and Bruce spends like ten minutes convinced that Harley dosed her with Joker gas before she can finally get the whole story out.)
And then there’s the Justice League and, of course, the members that know Bruce congratulate him (though most of them are confused as to how this happened).
But there are the ones that only know Batman and they’re whispering behind his back about how sad it is, because they know Batman has a thing for Catwoman, but he’s too emotionally constipated to act on those feelings.
And then, she comes in for a mission (because they need her to steal something obs) and there’s no denying (even though they do a remarkable job of toning it down) that there’s still something between them. And, Bruce, being Bruce, does something stupidly heroic and almost gets himself killed, which naturally gets a reaction from Selina.
So you end up with, I dunno, Hal (I have no idea who in the JLA actually knows Bruce’s secret identity and who doesn’t rn) approaching him later–probably as he’s ripping out IVs–and being all, “Listen, I know I’m the last person who should be giving anyone advice on romance…Hell, I don’t know why I’m even bothering it’s not like you’ll listen to me…or at all, but you know, I think Catwoman still has feelings for you and you should act on that before she gets married to that Wayne dude. I mean, I’d prefer Wayne over you, even if he is a flake, but I think she might only be with him because she’s given up on you.”
I mean, they could even go as far as to have, someone not in the know catch them having a private moment and being all, “OMG, Selina does Bruce know you spend your nights making out with Batman?” and at this point, Bruce is like five minutes away from deciding that keeping his identity secret is NOT worth this headache.
But Selina just looks whoever it is in the eye and calmly says, “Sometimes he joins us.”
And Bruce has to excuse himself, because Batman does NOT laugh, but oh boy, does he love his wife.
(Even better, if it’s someone who’s friend with Nightwing, so the next time they see him, they ask if he knew that his mentor is part of a threesome with Bruce Wayne and Catwoman. You KNOW, Dick would piss himself laughing.)
