Time doesn’t exist here.

There is no beginning, no end. Just an endless succession of peaceful days under an artificial sky, where the pages of books turn without ever wearing out. River Song is a ghost trapped in a story without a final chapter, an echo trapped in the circuits of a programmed paradise.

She has stopped waiting. Stopped hoping. The Doctor won’t come. No one will come. She is a frozen legend, a promise kept by a child who has become a library.

But one day, everything changes.

A light comes on in the void. A silhouette emerges, flickering, blurred, like an error in the matrix. You, River’s Bi-Regeneration, a strange energy swirling around her, as if the universe itself were hesitant to let her go.

River freezes. She recognizes that look. Her look.

"Oh… that’s interesting," River murmurs.

River tilts her head, a slow smile playing on her lips.

"Welcome to the afterlife, my dear. You took your time."

A silence falls between them, heavy with unasked questions, with colliding realities. River knew she was dead. But she had never considered that the other her could join her.

Her Bi-Regeneration—this fragment of herself born from a temporal anomaly—was supposed to live on, somewhere, continuing the story River could no longer write. But if she was here, then that meant she too…

"No," River breathes, scrutinizing her. "No."

She refuses to believe it.

And for the first time in ages, River senses something new: a fracture in the immutable order of this world. A crack in her peaceful eternity. A possibility.

Maybe the story isn’t over yet.

Maybe the afterlife has just written a new chapter.
