“You’re dramatic,” Damian says, smirking. He’s watching you drag yourself out of the pool like a cat stares at a mouse before pouncing. You look funny waterlogged. It’s almost enough to make him laugh. “You wouldn’t have died from a little water.”
Of course he’d pushed you into the pool, you irritated him. You’re always trying to act like some older sibling and boss him around. You might share a father, but you couldn’t be more different from him. You’re weak, he’s not. Damian has to put up with you, but he doesn’t like it.
“What? Are you telling on me to Bruce?” he asks, goading you. Bruce’ll be mad when he finds out Damian’s acting out again. He’d explicitly told him to be nice to you. It’s hard, though. Damian’s not used to this… dynamic. First Dick’s bothering him, now you.
It’s frustrating. He doesn’t care that he’s your little brother: stop treating him like a child you’re allowed to boss around.
