The Final Fates of the Core AA Support Group

The true heart of *Mom* was the AA support group, a powerful circle of women who relied on each other for survival. The series finale, which aired in May 2021, provided satisfying, emotional closure for the remaining characters, solidifying the theme of enduring sobriety and the strength of the "chosen family."

Bonnie Plunkett and Adam Janikowski

• Bonnie's Final Scene: The show concluded with Bonnie leading an AA meeting, acknowledging a newcomer's fear and offering a message of hope and strength, confirming her role as a leader in her recovery community and her acceptance of her past.

Jill Kendall: Motherhood and Marriage

Jill Kendall’s arc was marked by dramatic highs and lows, including a painful relapse and the struggle to find meaning beyond her inherited wealth.

• Relationship with Andy: Jill found lasting love with Andy, a police officer. In the final season, the couple got married, which was a major step toward stability for her.
• Motherhood: Jill's most significant development was her journey to motherhood. After a heartbreaking miscarriage, Jill and Andy decided to adopt a baby, giving her the family she always longed for and cementing her commitment to a sober, fulfilling life. This storyline beautifully concluded her search for purpose.

Marjorie, Tammy, and Wendy: The Unbreakable Trio

The supporting women of the support group also received meaningful closure, emphasizing their roles as essential pillars of the community and each other's lives.

• Marjorie Armstrong-Perugian: The wise sponsor continued her role as the group's moral compass. Her final arc focused on her stable marriage to Victor and her continued commitment to sponsoring newcomers, including her emotional separation from Christy as a sponsee. Marjorie's final fate is one of peaceful, continued service in sobriety.
• Tammy Diffendorf: Tammy’s arc was about redemption and finding a true career. After her release from prison, she successfully started a construction and contracting business. Her final scenes show her integrated into the group, having found a loving, non-romantic "chosen family" with Bonnie and the others, and a stable future as a working professional.
• Wendy Harris: Often the butt of jokes about her quiet nature and her job as a nurse, Wendy’s ending was subtle but powerful. She remained a steadfast, loyal, and sober member of the group, a reminder that not every recovery story is dramatic, but all are equally important. Her presence solidified the idea that the group's strength lies in its diversity and unbreakable bond.

The Plunkett Grandchildren: Violet and Roscoe

While the focus shifted to the AA group, the fates of Christy's children, Violet and Roscoe, were quietly resolved earlier in the series.

• Violet Plunkett (Sadie Calvano): Christy's oldest daughter, Violet, was written out after Season 3. Her character, who struggled with her own teenage pregnancy and difficult relationships, decided to leave home to pursue a more independent life. This was a necessary step to narrow the show's focus to the women's recovery and the AA meetings.
• Roscoe Plunkett (Blake Garrett Rosenthal): Christy's son, Roscoe, was also phased out after Season 4. His departure was explained by him going to live with his father, Baxter (Matt Jones), who had also found sobriety and a more stable life. This allowed Christy to focus fully on her law school aspirations without the daily burden of childcare.

The ultimate success of *Mom* lies in the fact that every main character, from Bonnie to Christy, and Jill to Tammy, found a form of peace, stability, and sobriety. The show proved that recovery is not a destination but a continuous journey, and that an AA support group can truly become an enduring, loving family.
