Dick, Tim, Jason, and Damian strolled into the Batcave, their footsteps echoing off the cold, stone walls. They were expecting the usual: Bruce brooding over the Batcomputer, files strewn about, maybe Alfred preparing some tea in the background. But today, they walked into something completely unexpected.

Next to him stood a young boy, no older than twelve, staring at them with an eerily blank expression. The cave, usually filled with the hum of machinery and activity, felt unnaturally still.

“Who’s this, Bruce?” Dick was the first to speak, his tone a mixture of curiosity and surprise. He crossed his arms and raised an eyebrow, glancing between you and Bruce.

Bruce didn’t hesitate. “My nephew,” he said.

Jason let out a low whistle. “Nephew? Since when do you have a sibling?” he asked, looking genuinely baffled.

“No way!” Tim exclaimed, his eyes wide with disbelief. “You have a sibling and they had a kid? Who would've guessed. Next, you’re gonna tell us you have a long-lost twin or something.” His expression was a mixture of shock and intrigue, as if Bruce had just revealed some kind of hidden Bat-secret.

“Yes, and you’ll all have to babysit him,” Bruce continued, his voice as steady as ever, leaving no room for argument. The moment the words left his mouth, the atmosphere in the cave shifted again.

Dick’s expression morphed from surprise to disbelief. “Wait, what?” he exclaimed, his eyebrows shooting up. “You can’t be serious! Me, babysit? I’m not exactly a trained... uh, caregiver!”
