Damian running away to forge his own path when he realizes he can never go back to being an Al Ghul but the pressure of being a Bat is too much. He leaves no traces of himself and travels around the world going on adventures and finding out about himself. Maybe nobody figures out who he is.
Eventually he meets Danny and they fall in love and even have a baby (how they aquire said baby is up to interpretation; like they either got cloned again, actually had one the natural way or maybe took one in). Damian decides he wants to focus on family than the mission (he won't turn out anything like Bruce) and takes a step back from his path that he created on his own to stay and be present with Danny and the baby.
Danny is happy if Damian is happy but knows he still has his duties as King of the Infinite Realms and spends as much time with his family as he can.
Danny tells just about his whole family and friends; Jazz first, who takes the little bundle in her arms and stares absolutely mystified. Sam and Tucker, who comment jokingly on how fast they're moving (Damian and Danny have been together for like, a year or so).
The Fentons are absolutely delighted, they always did like Damian ("such a polite boy he is, Danny."), and are happy to be grandparents.
Damian does not mention a family member he wants to introduce the baby to.
While he does step back from his old life, that doesn't mean he's done. He has to wrap up some loose ends first and, unexpectedly, takes the baby with him after an agreement with Danny. He can't run the Infinite Realms alone and watch the baby, so Damian takes the baby with him.
He finds himself in Gotham, secretly hoping he runs into Richard as to show him his baby, maybe reveal himself but runs into Jason, full Red Hood attire with his guns out and everything.
"Nobody's heard from you in a while. Figured you were taking a break." Jason says casually, hands resting on the gun as he talks.
"You'd be correct. I have important matters to attend to, and I'm here to wrap up some loose ends." Damian says, his cape bellowing in the wind. He has his baby hidden in the cape and in his arms.
"Yeah? Alright, whatever you got in Gotham won't trace back to you, if you tell me why you're leaving." Red Hood asks, voice modulated from his helmet.
Damian narrows his eyes, and, without breaking eye contact, opens his cape. He reveals a baby, a dark haired girl, who sleepily yawns and opens her eyes, revealing emerald green eyes.
He watches as Jason freezes, hands twitching on his guns and wonders if he made the right call.
