"A sinner comes before you: Cersei of House Lannister."
Septa Unella visits Cersei, who cowers in her dark cell. Broken, Cersei confesses to the High Sparrow, admitting to her affair with Lancel, but denies the charges of incest. The High Sparrow maintains that she must still face a trial to separate truth from falsehood. Cersei begs for mercy, and the High Sparrow permits her to return to her son – after she atones for her sins.
A team of septas roughly scrub Cersei and slice off her long hair. Bleeding, she's brought naked before the crowd on the steps of the Sept of Baelor. The High Sparrow announces Cersei's sins and explains her penance – a walk of shame through the city streets. Cersei descends the stairs with Unella behind her, chanting "shame" and ringing a bell. The masses taunt Cersei, throwing food and feces. By the time she reaches the Red Keep, Cersei is covered in filth; her feet are raw and bloody. Grandmaester Pycelle and Kevan Lannister await her arrival, but only Qyburn moves to greet her. He covers her with a blanket and introduces the newest Kingsguard member, a monstrous man whom the maester explains has taken a vow of silence. The lumbering figure scoops Cersei in his arms and carries her safely inside the castle.
