Still thinking about how Significant Other (2022) ended? Here’s a full breakdown of the ending, key final moments, major twists, and the deeper meaning behind the film’s conclusion.
The ending of “Significant Other” reveals that the alien creature, which initially took the form of Harry after killing him and hiding his body, has been experimenting with human emotions—particularly love. Ruth’s discovery that Harry was actually an alien in disguise led her to realize that the creature was capable of experiencing human feelings, such as love, because it had taken on Harry’s memories and emotions during their interactions. This revelation explains why the alien couldn’t kill Ruth outright; unlike other predators, it developed a complex attachment to her, motivated by Harry’s love for her. The creature explained that it wanted to take Ruth to a distant planet where they could live together, free of Earth’s chaos, because it believed love was a unique and powerful emotion that made humans special. Ruth, however, saw the alien’s capacity for love as a weakness and a danger. She managed to trick the creature into the ocean, where a shark attacked it, but the alien’s regenerative powers allowed it to survive. Ruth then escaped the forest, leaving behind the creature, which was injured but still indestructible due to its alien nature. As she drives away, she turns on the radio and hears the creature’s voice warning her it will find her, illustrating its persistent threat. Meanwhile, the sky fills with falling red stars, symbolizing the invasion of Earth by many more aliens like the one Ruth encountered. The film ends on a bleak note, suggesting that humanity’s capacity for love has made them vulnerable to these alien beings. The ending leaves viewers questioning whether these aliens will also experience human emotions or if they will continue to manipulate their feelings for their own survival, hinting that Earth may soon fall under alien domination, with Ruth’s fight for freedom seeming almost hopeless in the face of this overwhelming invasion. The story implies that while love is a powerful human trait, it could also be the very thing that puts humanity at risk in a universe filled with emotion-capable alien predators.
