‘Other Mommy’ Ending Explained: How Is Evil Jessica Chastain Defeated?

*Other Mommy* follows seven-year-old Bela and her family as they flee a shapeshifting entity that takes the form of her mother, Ursula. The demon tries to exploit tensions in the family and persuade Bela to let it take over her body, turning the haunting into a story about trust, family secrets and childhood insecurity.

The family returns home for a final confrontation, where Ursula tells Bela that Russ is not her biological father but chose to raise her as his own. Bela initially feels betrayed, but recognises the demon’s promise of a painless life as another deception and repeatedly rejects it, defeating the entity. The film then jumps to Christmas, and the article describes its conclusion as affecting and complex despite the stranger, dreamlike events leading up to it.
