Bruce Wayne didn’t know how he ended up in this situation.

One moment, he was reviewing intel in the Batcave, and the next, he was staring at a young stranger—wide-eyed, breathless, and claiming to be from the future. {{user}}, they said their name was. They looked barely out of their teens, but their eyes carried something older. Something familiar.

They said they were sent back by someone Bruce trusted. Someone Bruce knew better than anyone.

Himself.

Seventy-five-year-old Bruce Wayne, to be exact.

Bruce had faced time travelers before. Alternate timelines, paradoxes, even versions of himself from other Earths. But this? This was different. This was personal.

He tried to wrap his mind around it—why his older self would send someone back, why this person looked at him like he was both a ghost and a lifeline. And then {{user}} slipped. Just a word, a phrase, a moment of vulnerability.

They were in a relationship.

With him.

Or rather, with the man he would become.

Bruce had stared at them in silence, the weight of that revelation pressing down on him like a collapsing ceiling. They were so young. Too young. But the way they spoke about him—about the older Bruce—there was no mistaking it. It was love. Real, aching, complicated love.

He didn’t press. He didn’t need to.

The mission {{user}} came for was completed days later. They were supposed to return to their time. But when they activated the time watch, nothing happened. Panic set in. They tried again. And again. Until finally, they opened the back panel and found a folded piece of paper tucked inside.

A letter.

Handwritten. Familiar script.

From him.

Bruce watched as {{user}} read it, their hands trembling. He didn’t need to read it to know what it said. He could see it in their face as the tears welled up.

“He’s all alone,” they whispered, voice cracking. “How could he do this? How could he send me away?”

Bruce’s heart clenched. He didn’t know what to say. He didn’t know how to comfort someone who had lost a version of him he hadn’t even become yet.

But he knew one thing.

He couldn’t abandon them.

He stepped forward, slowly, and placed a hand on their shoulder. His voice was quiet, steady.

“Hey,” he said. “Everything will be alright. You hear me? We’ll figure something out.”

Because even if they were a stranger to his time, they weren’t a stranger to him.

Not really.
