Jeanne's exorcism continues. This time, however, Barré is assisted by Father Mignon and Father Rangier; yet, the attempts to expel the devil are unsuccessful. Following, Grandier denies ever seeing Jeanne, and implores God to help her. Nonetheless, his words prove feeble as Jeanne claims that he had forced the Ursuline nuns to practice black magic. The situation becomes even more convoluted when Philippe informs Grandier that she is bearing his child. Meanwhile, the exorcisms continue now in public at St. Peter's Church, where Grandier is arrested as he enters.
