When Bruce “died” all his kids ended up gathering together for the reading of his will. Things were split pretty evenly between them with certain assets going to certain people (the company to Tim, the Manor to Alfred etc). At the end of the will there is one last line
“Don’t let your brother turn into a supervillian.”
All of the siblings are busy arguing about who Bruce might be talking about except for Tim and Cass, who are standing away from the group. Tim has an amused gleam in his eye and Cass is staring him down.
“Don’t you dare.” She signs at him knowing full well that Bruce was talking about Tim.
“I’m going to take over the League of Assassins.” He signs back to her.
Which was always the plan, he just couldn’t leave right away. Dick giving Damian Robin was a perfect excuse. Also, Bruce was def alive just lost in the time stream and the league would have the resources he needs to find answers.
Six months later, over 100 bases blown up, and with coordinates to recover Bruce, Tim returns to Gotham. He’s not alone though. Oh no. Drake Industries has had a complete overhaul under the leadership of the teenage heir and if all of the new employees are ninja assassins thats for Tim to know and no one else.
When Bruce returns he gets swarmed with questions from his kids about which brother he was referencing at the end of his will and he gives them all a confused look.
“Tim of course. The kid borrows my morals like library books.” At this, Dick goes ashen.
Tim? Bruce had been concerned about Tim? Tim who has been off the grid for the last 6 months doing god knows what?
“Tim should have known I was referencing him. He should have told you and the fact that he didn’t means I should be concerned.” Bruce glances to his son who can’t contain his smile.
“It’s hardly my fault the Ra’s has the charisma of a used gym sock. Besides, at least I offer benefits and paid time off. Also you don’t have to worry about the LOA anymore. They all work for me now.” He smiles a bit wider and then disappears into the shadows.
Bruce, who wrote that last line after going through Tim’s Young Justice Records, simply signs. “Could be worse. He could have become Gun Batman.” Which unloads an entirely new floodgate of questions from those around him, but as long as his kids are safe, happy, and still walking a mostly moral line then Bruce is happy.
