Still No Idea How Danny Came To Live With Them But Boi Has Not Given Lots Of Details - Tumblr Posts
Fine line
Okay so we all know pre-reveal but already adopted Danny would question his whole life when he finds out about the vigilante life the Waynes are in but may I introduce you to:
✨Absolutely horrified Danny.✨
Basically he finds out that his seemingly normal family isn't so normal after all and due to the nature of the JL never responding to Amity calls he assumed that they were working with the government. This led to the realization that the family probably knows who he is (they really don't. They just think that he was a meta that doesn't want to deal with the crime-related life bs so they never brought it up) and they're probably in the midst of handing him to the GIW.
He's terrified, because god dammit he shouldn't have trusted a rich guy but he doesn't really have time to contemplate on his next move. Next thing you know Danny's holding a modified ecto gun that is now fatal to humans against Bruce.
The family is alert and ready to pounce on him, but they realized that Danny was shaking too much and his breathing was too ragged. His eyes are glossy and he's biting his lip like he's trying so hard to not drop the gun on his adoptive dad. Danny was having a panic attack.
