One of the most chilling and unforgettable scenes in 1923 isn’t fictional—it’s ripped straight from the darkest corners of real American history. The moment involves Teonna Rainwater, a Native American teenager forcibly enrolled in a Catholic boarding school, and the harrowing abuse she suffers at the hands of the institution’s cruel nuns and priests. Though audiences were shaken by the violence and emotional intensity of these scenes, what made them truly terrifying was the fact that they weren’t exaggerated for dramatic effect. In fact, they were understated. The history behind Native American boarding schools in the U.S. and Canada is a documented horror, often swept under the rug or mentioned only in passing. But in 1923, Taylor Sheridan chose to put it at the center of the show—and in doing so, revealed a truth many viewers were entirely unaware of: this wasn’t just history. For some, it’s still living memory

The most disturbing scene occurs when Teonna, stripped of her language, her name, and her cultural identity, is brutally beaten by the nuns for speaking her native tongue. Her hands are slapped, her face is hit, and her spirit is systematically crushed by the institution designed to “kill the Indian, save the man”—a real slogan used in official U.S. government policy at the time. This is not a dramatization; these methods were widely used in residential schools from the late 1800s through much of the 20th century. Children were taken from their families, sometimes forcibly, and placed in schools where their hair was cut, their clothing burned, and their names replaced with Christian ones. Speaking their tribal languages was forbidden. Any deviation from imposed behavior was punished severely—often with physical abuse, isolation, or starvation.

What truly surprised audiences—especially those unfamiliar with this piece of history—was the reveal that these schools were not fringe institutions. They were funded and operated by the federal government, often in partnership with religious organizations. Thousands of children went through them. Many never returned home. Mass graves have recently been discovered at the sites of these schools, especially in Canada, reigniting conversations about truth, reconciliation, and reparations. The fact that Sheridan chose to weave this narrative so authentically into a primetime drama shocked many viewers—but it also educated and outraged them. It forced the audience to sit with the discomfort of knowing that such cruelty was real, and it happened on American soil, sanctioned by American systems.

The surprise detail that stunned even the most informed viewers was how accurately the abuse mirrored real testimonies. In particular, Teonna’s story closely resembles those told by survivors who, decades later, have stepped forward to share their trauma. The episode in which Teonna is forced to kneel on raw rice—digging into her knees as punishment—was taken directly from the testimony of several Native American women who attended boarding schools in the 1920s and ’30s. Likewise, the burning of her sacred belongings and the renaming of Teonna to “Mary” are drawn from historical records. These weren’t inventions for shock value. They were lived experiences, recreated with brutal honesty.

But Sheridan didn’t stop at portraying suffering. The most powerful twist in the storyline—and perhaps the most meaningful—was Teonna’s refusal to be broken. She doesn’t become a passive victim. Instead, she resists. She fights back. She escapes. She kills her abusers. This is where the show deviates from the typical narrative of victimhood and offers something radical: justice, even if only in fiction. It’s a cathartic moment, and one that left many viewers both shaken and empowered. In real life, many survivors never got to fight back. Teonna’s revenge isn’t just plot—it’s symbolic. It speaks to generations of pain and the desire to reclaim dignity that was stolen.

Critics and historians praised this arc for its bravery and accuracy. Many were shocked to see such a sensitive and dark part of history portrayed with such care and intensity in a mainstream series. Native viewers in particular expressed gratitude for the spotlight being placed on something that had, for so long, been ignored. Others, unfamiliar with the topic, expressed disbelief and sorrow that they had never learned about these schools in their own education. It sparked nationwide conversations. Articles were written. Historians were interviewed. Viewers began researching residential schools on their own.

Another fascinating surprise was the performance of Aminah Nieves, who plays Teonna. Her portrayal was raw, heartbreaking, and deeply personal. In interviews, Nieves revealed that she herself is of Native descent and that playing Teonna felt like honoring the women in her own family who endured similar systems. She worked closely with cultural consultants to ensure accuracy and authenticity, and her performance reflects that commitment. It wasn’t just acting—it was ancestral storytelling, bringing the past to life not as entertainment, but as remembrance.

Beyond Teonna, the show’s broader message about generational trauma resonates across the timeline of 1923. The Duttons’ land struggles, the violence in Africa with Spencer Dutton, and the socioeconomic breakdown in Montana all intersect with this deeper undercurrent of colonization, loss, and resilience. It’s all connected. And Teonna’s arc makes that connection feel personal. By grounding the show’s most terrifying moment in historical fact, Sheridan elevates 1923 from Western drama to historical reckoning.
