Afterimage (слэш)

"If you had it to do over again, and you could change everything, would you?" When all appears lost, Dean Winchester—battered, weary, guilty, and alone—is given the opportunity to travel back in time and live his life over again with the promise that if he makes the one choice he was too afraid to make before, he will be able to change the future, and avoid the loss of everyone he ever loved and everything he fought for. But how? After all, he knows time can’t be changed… But with the help of a mysterious entity, who may or may not be the actual God of Time, Dean discovers time can be rewritten.
Armed only with the ghosts of memories from his former life—afterimages of rewritten time—but not really understanding the gift he’s been given, the new Dean, an impossibly young 27-year-old hunter, once again turns to his estranged brother when their father goes missing. But when he takes a chance on forbidden love, will it be the key to saving the universe and averting the apocalypse, or will it only bring about the end even faster?
