Dr. Gloria returns to Oz after taking some time to recover from her attack. This time, the Wygert corporation decides to test an experimental drug on the inmates that would allow them to age faster. Although she's morally against it, she administers the drug to willing inmates--two of which are Cyril and Ryan O'Reily. To make matters worse, Ryan O'Reily constantly reminds her of how much he loves her. She confronts him about Keenan's death and he admits to doing it. All this confuses her and she confesses to Sister Pete that she thinks she may actually be in love with Ryan. Sister Peter warns her that his love is not unconditional and that she should be very careful. Back to the experimental drug project, after one of the inmates taking the drug dies, the project is halted. Dr. Nathan gets word from the prison authority that she will be investigated for her part in the program and her mishandling of the drugs causing the experiment to fail. For this, she could lose her job when all she was doing was following instructions.
