Season 1 of Big Little Lies built the mystery around the school fundraiser and the subsequent murder. It also revealed the true behaviour of Perry, the seemingly charming husband of Celeste, giving it a gut-punching ending. While the heart of the show remained the Monterey Five for sticking together and saving Bonnie by admitting that Perry slipped.
Season 2, on the other hand, showcases the aftermath of the traumatic incident with Mary Louise coming hard, battling for the children's custody with Celeste. Renata's marriage crumbles after her husband, Gordon, gets arrested for insider trading. In the final scene, the Monterey Five, Celeste, Madeline, Jane, Bonnie, and Renata, walked together into the police station, seemingly ready to confess the truth about Perry’s death.
The show has been renewed for its season 3, which is expected to drop in 2026. Here are the 5 plot points the show must answer in the new season.

Here are the 5 major plot points Big Little Lies Season 3 must answer
Big Little Lies has plenty of unresolved threads to pull on in season 3. Season 2 ends with the 5 Monterey confessing the truth behind Perry's death, which in itself builds a major cliffhanger for the new season. Here are the 5 burning plot points the new season must answer.
1. The Monterey Five’s confession
The Season 2 finale ended with the women walking into the police station, seemingly ready to confess the truth about Perry’s death. Therefore, season 3 ought to explore the fallout of the confession. Would they be fractured by the legal consequences? Bonnie had killed Perry to save Celeste and the family from his violent temper. So in this case, would it be treated as a murder or an act of defence? is only to be seen in season 3.
2. Celeste’s healing and parenting journey
By the end of season 2, Celeste has won the custody of her kids; however, the children are still processing the trauma of seeing their father's abusive nature and the event that follows. Celeste should struggle again to build a safe and stable home for her family while also dealing with her own grief.
3. Bonnie’s guilt and marriage
Bonnie in Big Little Lies is struggling with guilt and regret by the end of season 2. Her character arc in season 3 would be important, as she was the one who pushed Perry to his death. No matter how noble her intent was, she had killed someone and was carrying the heaviest emotional burden.
Secondly, her confession to Nathan that she never truly loved him also left their marriage hanging by a thread. Season 3 could unpack her guilt, her future with Nathan, and her personal identity outside the secret.

4. Madeline and Ed’s
Mandeline and Ed's relationship is also showing some cracks after healing from the incident of his infidelity. Season 3 of Big Little Lies should explore whether their relationship would survive long term or see a tragic end, especially after the confession at the police station they are about to make.
5. Mary Louise’s next move
Mary Louise, Perry's mother, was left defeated in court in Season 2 of Big Little Lies, but her presence and influence were seismic. It is to be seen in season 3 if the character resurfaces again with another plan to disturb Celeste's life. Her role might become important after the Monterey Five's confession about the killing. Season 3 of Big Little Lies could also witness some new antagonist other than Mary to fill her shoes.
