Orphan Black Recap Season 3, Episode 6, "Certain Agony of the Battlefield"

BBC

Wracked by high fever, Sarah Manning (Tatiana Maslany) slips into delirium midway through “Certain Agony of the Battlefield” and comes face to face with the origins of Orphan Black. Infected via blood transfusion with the Castor clones’ STD, she passes through a tunnel in her mind’s eye only to greet Beth Childs in a gauzily lit kitchen of the afterlife, where she receives a message from her late “sestra” to the tune of the straining score. “We do terrible things for the people we love,” Beth says, referring to the impenetrable Paul Dierden (Dylan Bruce). “Stop asking, ’Why?’ Start asking, ’Who?’” Thus freighted with delusions, dream sequences, flashbacks, and musical interludes, “Certain Agony of the Battlefield” strings together a series of arresting images, but by the time Paul unwraps a grenade from his palm in the final minutes of the episode, these flickers of style add up to little more than a placeholder for dramas still to come.
