The ending of We Were Liars reveals that Cadence’s cousins Johnny and Mirren, along with her love interest Gat, actually died in the fire they all set at the Sinclair family’s Beechwood Island mansion, Clairmont, the previous summer. She has been seeing and talking to them as ghosts or trauma-induced hallucinations while repressing her memories of the fire and her role in it.

Core twist of the ending

  • Cadence and the other Liars agree to burn down Clairmont to protest the Sinclair family’s greed, racism, and inheritance battles, believing they will all safely escape.
  • The plan goes wrong: fuel is placed near the stairs and in key exits, and not everyone gets out in time when the house goes up in flames.
  • Cadence survives but suffers a head injury, severe trauma, and partial amnesia, while Johnny, Mirren, and Gat die in the fire.

Cadence’s memory and guilt

  • After the accident, Cadence spends a year with migraines, memory gaps, and fragments of the night of the fire, which her family refuses to fully explain.
  • When she returns to the island, she sees the Liars again and thinks they are alive, but they are manifestations tied to her repressed memories and grief.
  • As the truth comes back, she realizes that her push to “burn it all down” helped cause the deaths of the people she loved most, and she is overwhelmed with guilt and responsibility.

Final emotional resolution

  • Cadence finally remembers that she ran back into the burning house to save the dogs, a choice that contributed to the chaos and tragedy, and she must face that selfish and impulsive part of herself.
  • She says goodbye to the Liars—accepting that they are gone—and begins to move forward, no longer idealizing the Sinclair image of perfection and recognizing that she shares the family’s flaws like lying and selfishness.
  • In some recent TV interpretations, her grandfather Harris knows she caused the fire but publicly calls it an accident, using that secret to pressure her about inheritance, while Cadence chooses to reject the fairy-tale Sinclair legacy and define her own path.
