Still on that time travel fix-it trope with Jason being the one sent back. He wakes up as a child again, maybe a week after he's caught stealing the tires of the batmobile. Still not adopted, but he's very aware that Bruce is keeping an eye on him. Jason isn't about to repeat history and let Batman adopt him again (maybe they were getting better back when he was an adult, but he also has a lot of regrets and wants a break from vigilante life. After everything he's been through, he's owed that, right? So this time around, maybe he shouldn't become a Wayne). But Bruce (both as Batman and as himself) keep trying to talk to him. Jason manages to escape every time, but Bruce is a clever man and will find a way if Jason doesn't take care of this now.
At a time where Batman is busy with a rogue or somewhere he can't keep an eye on Jason, Jason takes the opportunity and goes to New York/Bludhaven wherever Dick is living. Because he remembers how angry Dick was at Bruce then. If anyone would help Jason stay out of Bruce's grasp, it would be him.
Dick answers the door to this little kid wearing worn out street clothes glaring up at him. Dick, immediately on the defense, glares back. They do this for several minutes because they're both stubborn like that. Then...
"Stop who?" Dick asks, because maybe this kid is in trouble and needs help?
"Batman," Jason says like it's obvious. Before Dick can deny/deflect/shut the door in his face, he continues: "He keeps trying to kidnap me and make me Robin."
Dick's mind blanks out as pure, unfiltered rage courses through him. Because now he doesn't care about what exactly this kid knows about him or Batman. How dare Bruce try and replace him?!
"The fuck he isn't," Dick snaps, and Jason smiles in relief. Because Dick will stop this madness.
