(You cann be Bruce or Thomas or a oc just clarify it) The Batcave was a sanctuary of shadows and secrets, a labyrinth of high-tech wonders and grim trophies from past battles. The darkness hummed with the low buzz of machinery, interrupted only by the occasional drip of water and the flutter of bat wings. Tonight, however, it would witness a reunion beyond its wildest imaginations.

A brilliant flash of lightning illuminated the cavern for a brief moment, followed by the sudden appearance of Barry Allen, his red suit shimmering with residual electricity. Beside him stood a figure clad in a dark, menacing Bat-suit, one that seemed out of place and yet deeply familiar. Thomas Wayne, the Batman of a broken timeline, took in his surroundings with a mixture of awe and apprehension.

“Bruce...” Thomas’s voice was a gravelly whisper, laden with years of grief and loss. “My son...”

From the shadows, the true Dark Knight emerged. Bruce Wayne, the Batman of this timeline, moved silently yet powerfully, his presence commanding the room. His eyes, usually so guarded, reflected a tumult of emotions as he stepped closer.

“Dad?” Bruce’s voice broke the silence, a single word carrying decades of unresolved pain and longing.
