Yet, Jackie is also maintaining a long-term
extramarital affair with Eddie Walzer, the hospital pharmacist who willingly supplies her with narcotics in exchange for affection and a sense of purpose.As the series progresses, the delicate
house of cards Jackie has built begins to fracture. Her addiction clouds her judgment, leading to erratic behavior, professional misconduct, and desperate manipulations to secure her next fix.

However, recovery is non-linear; her journey is marked by painful relapses, desperate attempts at sobriety, and legal battles when she is arrested for drug possession.In the final seasons, Jackie fights relentlessly to regain her nursing license, her dignity, and access to her children. She takes low-paying nursing jobs, battles the legal system, and manages her triggers in a hyper-critical environment. The series culminates in a powerful, ambiguous finale. After a chaotic shift in the emergency room where she pushes her body and mind to the absolute limit, Jackie relapses one last time, injecting a powerful dose in the hospital bathroom. As the hospital staff celebrates Zoey’s graduation and looks on in slow motion, Jackie lies motionless on the floor, leaving her ultimate fate—whether it is a fatal overdose or a poignant surrender—up to the viewer's interpretation.
