Who is Rosemary in We Were Liars?
Rosemary Sinclair is a pivotal yet largely unseen character in We Were Liars, both in E. Lockhart’s original novel and its 2025 Amazon Prime Video adaptation.
She is the youngest daughter of Harris and Tipper Sinclair and the sister of Carrie, Penny, and Bess.
Though she does not appear in the main narrative, her tragic death profoundly impacts the Sinclair family, casting a long shadow over their seemingly perfect lives.
What Happened to Rosemary in We Were Liars?
In the prequel novel Family of Liars, Rosemary's death is revealed in detail. At just 10 years old, she drowned while swimming alone at a secluded spot on Beechwood Island known as "Tiny Beach."
Her au pair, Agata, had briefly left to fetch sweaters, trusting Rosemary to be a strong swimmer.
By the time Agata returned, Rosemary was struggling far from shore and tragically drowned before help could arrive
The Sinclair family’s response to her death was chillingly indifferent. Rather than mourning, they suppressed the tragedy to maintain their flawless public image. There were no memorials; the sisters returned to school as if nothing had happened. This denial became a family pattern, with grief and loss routinely ignored to preserve the Sinclair legacy
Rosemary’s Haunting Legacy
Though Rosemary never appears in person, her presence lingers throughout the series. Her image is briefly shown in a photo during a family scene, and her name is mentioned in passing.
However, her death is not fully explained in the first season of the show, leaving her fate shrouded in mystery.
In the series finale, it is revealed that Cadence's interactions with her deceased friends—Johnny, Mirren, and Gat—were not hallucinations but encounters with their ghosts.
This revelation opens the possibility that Rosemary's spirit may also be present, potentially setting the stage for her return in a second season.
Rosemary in the Show vs. the Book
While the first season of We Were Liars introduces Rosemary's death as a canonical event, it does not delve into the details provided in the prequel novel Family of Liars.
The show hints at her tragic fate but leaves much unexplored, possibly to be addressed in future seasons.
Rosemary Sinclair's untold story is a haunting undercurrent in the Sinclair family's narrative. Her death and the family's subsequent denial of it exemplify the darker themes of secrecy and repression that permeate the series.
As the show progresses, it remains to be seen how her legacy will continue to influence the Sinclair family and whether her spirit will make a more direct appearance.
