Event: Cersei Lannister - New Follower/Prisoner (Political Wins)

Episode 10: The Winds of Winter at 18:22
Cersei takes Septa Unella prisoner, tying her down to a table as she tortures her. "Confess. It felt good. Beating me, starving me, frightening me, humiliating me. You didn't do it because you cared about my atonement. You did it because it felt good. ... I killed your High Sparrow, and all his little sparrows ... because it felt good to watch them burn. It felt good to imagine their shock and their pain. No thought has ever given me greater joy." (New Follower/Prisoner)
