While I'm sure bad guys in Gotham have learned over time that the Bats don't kill, that even after bashing your teeth in they'll flag down an ambulance or dump you unceremoniously at the ER, it's still a shaky trust.
One that is easily shaken seeing a child wielding a sword in the dead of night; nobody wants to learn how that is handled nonlethally. Or bad guys just surrendering one late night after running into an alley and Nightwing's standing over their unconscious buddy, holding the gun he wrestled away. They watch Red Hood break into the place they're robbing with a crowbar in hand and just decide they'd rather not chance it. They see a shadow that could be Black Bat and-- you get it.
idea that league of Assassins has connections and deals with the ghost Zone/ infinite realms. Ellie gets destabilized and Danny needs help; he ends up going to frostbite and Clockwork. They tell him about the deals that a lot of the ghost Zone has with league of assassins. He panics because of the Assassins but they make it very clear that they can help. Danny is about 14 And Damien is turning 13.( I know Damien is supposed to be with his dad at this point but just go with it)
Ellie ends up the de Aged and Danny uses an artificial womb thing that Talia uses for Damien. Danny and Damien become friends during this time due to Talia and Ras wanting Damian to have good connections with the infinite realms.
There's an attack on the league that ends up with Damien getting very hurt in the lab that has Ellie, it affects something and Damien's DNA ends up helping Ellie grow. The DNA helps stabilize her but it also gives her another donor. Damian leaves to train with his father not long after the incident but he does know there is a chance that she is technically now his kid though it is never confirmed while he is there.
I'm just imagining Damien knows weirdly niche things due to Danny and the bat family is wondering why he knows things like obscure memes or has opinions on fast food.
The bat family has to interact with the League of Assassins and Damien asks his mother how Danny and Ellie are and if the accident caused problems with development. Talia then reveals that his DNA did end up integrating with Ellie and that technically he is the father. He asks if she can get them in contact and he end up able to. When This entire thing happens All the family is fighting for their life and they're in a separate area so no one knows what this conversation is.
They get into contact and end up meeting up when Damian is on a mission outside of Gotham. Damien leaves Gotham to meet up with them constantly and that pings on his family's radar. They follow him thinking he's taking down some sort of group without backup or he is contacting the league. What they find is not what they expect.
They Find is Damien talking with Danny cuddling under a tree while Ellie plays with Cujo. They don't realize Ellie is with them at first until Danny calls her over for lunch and she calls Danny and Damian mom and dad. They then proceed to question when Damien became a teen dad.
