Cersei visits the High Sparrow in an ancient chapel beneath the Sept of Baelor. He explains there will be a trial for the Tyrell siblings; high and low alike, true hearts will be laid bare. "When we strip away your finery," he asks the queen mother, "what will we find?" With that, he ushers Lancel Lannister into the chapel and tells Cersei that the young man has fully unburdened himself about their relationship and other sins of hers. Cersei tries to leave, but is taken into custody and locked in a cell.
