Congrats! You are both the Parents!
A new idea spawned.
A Danny/Bruce/Talia idea again.
Like my Bittersweet and Sweetheart Exes prompt I wrote out a while ago.
But lets add in core/babies Dan and Ellie... Is this mpreg? eh I guess?
So hear me out.
Danny is an adult in this BTW. (Maybe a few years younger than Bruce?)
Danny is in Gotham? (maybe a different place?) and he's with a redeemed Vlad (whose acting like a second father figure for Danny, OR maybe he is because he's now dating Maddie and Jack? Good Fenton parents? IDK) for some Gala event since Danny is his godson. Danny's been stressed out lately and everyone thought it would be best if he got out of Amity for a while, clear his head. He's only at the event because Vlad promised to buy out the neighboring space museum the next day if he went with Vlad for the night.
Anyways Danny is at this event because of normalish reasons.
Bruce/Batman and Talia are there for their own reasons, it just so happened that they were both at this event (Talia for a mission? Bruce for his own? Maybe it connects later?) Of course Talia flirts with her Beloved when she has chances and Bruce slowly caves to her because he still holds feelings for the woman.
During their interactions they stumble across Danny, maybe they run into him outside in the garden grounds? They went outside to talk about their 'missions' while Danny just wanted some air, Danny apologizes for interrupting them and goes to leave but Bruce decides its best to have a witness in case they need alibis later starts being Brucie (Talia rolls her eyes amused at the idiot mask) and says Danny doesn't have to go.
The three actually, somehow hit it off. Even Talia is a bit more charmed with Danny than she thought she would be. (Maybe because he didn't bat an eye when she mentioned she could fight, she's used to men thinking because she's beautiful/a woman she is a 'delicate flower', Danny knows she's deadly, can sense it, says so as much when she asks eventually and mentions how he grew up with a badass mother and his big sister could beat him into the ground in hand to hand, bad with guns though. He even says he has two female friends who could kick his butt as well, one scrappy (Sam, I headcanon Sam would be a scrappy fighter) while the other has training (Val))
AND because this mission they both were on is more for recon until later, the three are flirting for a while, drink a bit, and eventually find themselves in bed in someone's hotel room that night.
When Danny wakes up the next morning, he is alone, with a note from them (Bruce wrote it, Talia only signed it because Bruce convinced her to be polite at least) The room has been paid by one of them for the day, along with any food he could order for the day.
Meanwhile Batman and LOA Talia are dealing with each other/missions.
But here's the thing. A few months go by and Danny is now trying to figure out how to contact them both, Bruce is easy to find but he'll have to explain to him a few things to the himbo (who might not be as much as a himbo he thought he was? 'Brucie' seemed smarter by the end of the night before they fell into bed together), while Talia seemed like a ghost (Ha! He's still funny) and next to impossible to find (though Bruce might know where she is? They seemed very close, like they knew each other before hand)
The reason?
It turns out the two Danny fell in bed with MIGHT have been a bit more liminal than he first thought (Talia more than Bruce but both are very death touched) and the two cores of his once clones (Ellie and Dan) he had been storing inside himself might had decided that the two were liminal enough to use their DNA's/pieces of their spirit/souls and now Danny has two tiny cores incubating inside of himself and he really doesn't wanna be that person that hides this from the person(s) they had a one night stand with.
So yeah... Now Danny is making his way to Gotham to talk to Bruce (and maybe Talia if Bruce has her number?) about the whole half ghost thing, the cores inside of him, and the future kids they are having....
Oh boy....
