She believes Cyril's actions although violent are the cause of his diminished mental capacity and he's therefore not completely responsible. During a session Schibetta reveals that he was raped by three men. Sister Pete recommends he talk with Dr. Nathan to help him deal with his attack. At a later time, Sis. Pete met with Adam Guenzel, who's now completely under Schillinger's control. Her attempts to get information from Adam are to no avail as he reports that things are fine. She knows he's lying but getting the truth is harder than it seems. She decides to put the query to the three inmates she knows have insight: Beecher, Said and Schillinger.
