Remembering his last request to her, Sister Pete promptly sits down and proceeds to finish polishing Nat's nails.

Sister Pete recommends he talk with Dr. Nathan to help him deal with his attack. At a later time, Sister Pete met with Adam Guenzel, a new inmate who is now completely under Schillinger's control. Her attempts to get information from Adam are to no avail, as he is too afraid of Schillinger's wrath to tell anyone about the abuse he suffers. She decides to ask the three inmates she knows have insight: Beecher, Said and Schillinger. When she asks them to speak up on anything they may know about Guenzel's case, none of them responds. Angry and frustrated, she dismisses them and refuses to see any of them for future sessions.

It is the COs who end up taking the puppet from Cyril. She also oversees the evaluation of Keller, who's now on Death Row. When the governor lets Sister Pete know that Cyril will undergo Electroconvulsive therapy, to make Cyril "seem" normal enough to execute, she is distraught, knowing there is nothing she can do to stop it, and takes a walk in the meditative maze. She watches in horror when Leo Glynn stumbles to the Awards Ceremony, covered in blood and dies on the ground. Even though she and Warden Glynn often had disagreements, she agreed that he was "the best man for the worst job".

Finally, she evaluates inmate Lemuel Idzik who was sent to Death Row for killing Omar White. When he tells her that he killed Omar to intentionally be put on Death Row after he lost all hope in living after meeting who told him how the universe would ultimately be doomed, she views that as him being self-destructive (and a way of committing suicide) and successfully has his sentenced commuted. Finally, she witnesses the execution of Cyril O'Reily, along with Suzanne Fitzgerald after his stay ends.
