Alice kills in His & Hers because she believes murder is the only way to both avenge her daughter Anna’s past trauma and forcibly pull her broken family back together. Her actions mix revenge with a twisted idea of “restorative justice,” turning her into a vigilante who decides that Anna’s old friends must pay for what they did.

What Alice Finds Out

  • Alice discovers that Anna’s former school friends Rachel, Helen and Zoe schemed in a way that led to Anna being sexually assaulted as a teenager, a secret Anna never fully faced.
  • After baby Charlotte dies while in Alice’s care and Anna disappears from their lives, Alice becomes consumed by grief, guilt and anger toward anyone she blames for Anna’s suffering.

Alice’s Main Motives

  • Revenge for Anna’s rape : Once Alice realizes that Rachel, Helen and Zoe orchestrated the situation that led to Anna’s assault, she feels they “deserve” to die and decides to punish them herself.
  • Fixing her family by force : In her letter, Alice explains that each killing had a purpose: “Killing Rachel brought you home, killing Helen kept you here, and killing Zoe gave you the family you lost,” meaning Zoe’s death lets Anna and Jack raise Zoe’s neglected daughter.

How Twisted Her Logic Is

  • Alice convinces herself that the murders are a kind of justice system that the police or courts will never provide, especially for what happened to Anna years ago.
  • At the same time, she treats killing as a way to rewrite their lives: bring Anna back, keep Jack close, and replace Charlotte with Zoe’s little girl, as if murder could repair grief and betrayal.

The Practical Side of Her Plan

  • She uses her experience as a cleaner and former school janitor to move around unnoticed, clean up scenes and leave minimal evidence.
  • Alice deliberately fakes dementia and leans into stereotypes about older women being frail or harmless so no one will ever suspect she is a serial killer.

In Short

Alice kills because she cannot accept what was done to Anna or the loss of her granddaughter, and she twists her love into something violent and controlling. In her mind, murder becomes both payback and a brutal way to rebuild a “perfect” family out of tragedy.
