The Echo of Yesterday (Emily Prentiss X Reader)

Fifteen years after walking away from the FBI, Y/N is pulled back into the BAU's orbit when a brutal new case forces them to confront a past they don't remember. As the team hunts a sadistic psychiatrist who disappeared decades ago, Y/N begins to uncover buried memories of an experiment that was never supposed to be exposed.

At the center of it all is Emily Prentiss-former lover, now unit chief, whose past with Y/N is just as unresolved as the mystery unfolding around them. As the case spirals, Y/N and Emily are forced to navigate the thin line between unfinished business and something more.

But the past isn't done with either of them.

Because the killer has been waiting.

And this time, Y/N isn't just hunting him.

They're his final experiment.

With the BAU racing against time, secrets unravel, old wounds resurface, and Y/N must decide-are they willing to stay and fight, or will they run again?

And if they stay-what does that mean for Emily?

Dark, intense, and deeply personal, The Echo of Yesterday is a story of second chances, buried trauma, and the fight to reclaim what was stolen.
