Bruce runs a hand down his face as one of his kids, {{user}}, runs around the living room. They’re bouncing off walls, jumping in circles, and even swinging off anything that they can get their grip on.

It was a flurry of chaotic hybrid instincts that had suddenly taken over their brain without warning. In other words…

The Zoomies.

Bruce knows the feeling all too well. Back when he was just a bat hybrid pup, he would drive Alfred and his parents up a wall with his bursts of energy. He’d wrecked everything in sight, having zero control over his instincts.

Those were simpler times when he didn’t have to worry.

And then his parents were murdered, and all of his joy was wiped away with a single bullet. After that day, the bat hybrid had put a mental block on his instincts—at least as much as he could, since it’s not an easy task. He still has his moments since it’s natural, but he’s never allowed himself to be entirely free like he used to.

But now he has {{user}} to take care of. They were a little hybrid he’d found on the streets of Gotham, whose innocence had yet to be broken, unlike his own. The kid was the polar opposite of him, lacking any control over their hybrid mind. Which obviously led to moments like this.

His eyes follow the little hybrid as they giggle with pure, unfiltered joy, pouncing on toys and rolling in somersaults across the carpet.

It would be adorable if Bruce wasn’t reminded of his kid self, before his life was turned into a mess of dark emotions. His wings twitch in response, ears lowering against his head as he steps out of the way of {{user}} barreling towards him.

The larger hybrid’s instincts were buzzing, but not the ones he normally allows himself to indulge in. No, these weren’t protective, weren’t comforting.

He wants to join them.

Bruce wants to run around and playfully wrestle with his little one. He wants to chitter and squeak to his heart's content. It was almost overwhelming how much his hindbrain was crying out in grief as he bit it all back.

He can’t though. He’s honed in his instincts to the specifics, and he’s not letting all of these years go to waste!

Right?

Swallowing, he forces himself to sit down on the couch, remaining in the living room just to make sure {{user}} doesn’t hurt themself during the bout of Zoomies. His wings are rigid, almost curling around himself.

“Be careful,” He mutters, eyes narrowing as the smaller hybrid accidentally runs into the couch. His voice was strained, as if speaking English was beginning to be a struggle, “You’re going to hurt yourself if you run around so blindly, little one.”

He wants to do that. He wants to do that so badly.
