The Baby Isn’t Kyle’s — Untamed Season 2 Premieres October 3, and a DNA Test in Episode 4 Will Shatter Everything

Netflix’s gripping crime thriller Untamed is set to return with its second season on October 3, 2025, and the latest bombshell has fans reeling: a mysterious baby tied to National Park Service agent Kyle Turner (Eric Bana) is at the heart of the new season’s drama, but a DNA test in Episode 4 will reveal the child isn’t his, threatening to unravel everything. Following the explosive success of Season 1, which topped Netflix’s global charts with 24.6 million views in its July 2025 debut week and earned a 79% approval rating on Rotten Tomatoes, Untamed Season 2 promises a darker, more personal mystery set in a new national park. Here’s everything we know about the October 3 premiere, the shocking DNA twist, and the chaos it will unleash.

Untamed Season 2: A New Park, A New Crisis

Untamed Season 1 captivated audiences with its slow-burn murder mystery set in Yosemite National Park, where ISB agent Kyle Turner and rookie ranger Naya Vasquez (originally Lily Santiago, now recast in secrecy) investigated a young woman’s death. The season’s emotional depth, driven by Kyle’s grief over his son’s unresolved murder and his struggle with alcoholism, resonated deeply, while its stunning cinematography made Yosemite a character in its own right. The finale, revealing dark secrets about Kyle’s mentor, Paul Souter (Sam Neill), left Kyle haunted and on the move, paving the way for a second season despite its initial “limited series” billing.

Season 2 adopts an anthology-like approach, shifting to a new national park—speculated to be Yellowstone, Zion, or Acadia—with a five-year time jump from the 2025 events of Season 1. The new setting introduces a fresh murder mystery, but the personal stakes are higher than ever with the introduction of a mysterious baby linked to Kyle. The revelation that a DNA test in Episode 4 will prove the child isn’t his has sparked intense speculation, promising to shatter Kyle’s world and reshape the season’s narrative.

The Baby Isn’t Kyle’s: A Shocking DNA Twist

The centerpiece of Season 2’s drama is a baby whose connection to Kyle Turner initially suggests a deeply personal tie. Promotional whispers and posts on X hint that the child, introduced early in the season, is believed to be Kyle’s, possibly tied to a past relationship or a fleeting encounter during his years of grief. The baby’s presence raises questions about Kyle’s life in the five years since Season 1, a period marked by his ongoing battle with alcoholism and isolation.

However, the bombshell drops in Episode 4 with a DNA test revealing the baby isn’t Kyle’s, a twist that threatens to “shatter everything.” This revelation could destabilize Kyle’s fragile mental state, undermine his credibility within the ISB, or expose a deeper conspiracy tied to the season’s central mystery. Fans on X are buzzing with theories: one user posted, “A baby Kyle thought was his? And it’s NOT? Is this a setup to frame him or something tied to his son’s killer?” Another speculated, “What if the baby’s real father is the man Kyle thought was dead? This is gonna break him.”

The DNA test’s implications extend beyond Kyle’s personal life, potentially intersecting with the new murder case. The baby could be linked to a key figure in the investigation—perhaps a victim, a suspect, or the returning character from Kyle’s past, previously revealed as a man he thought was dead. The secret letter from that same arc might hold clues to the child’s true parentage, tying the season’s emotional and investigative threads together.

A New Mystery in a New Park

Season 2’s anthology format moves the action to a new national park, with Yellowstone as a leading contender due to its dramatic geysers and wildlife, though Zion’s red cliffs or Acadia’s rugged coast are also possibilities. Showrunners Mark L. Smith and Elle Smith have teased a “new canvas” for Kyle’s next case, with Eric Bana telling TV Insider, “Kyle’s thrown into a park he doesn’t know, with stakes that hit closer to home than ever.” The new mystery is expected to involve a series of deaths or a supernatural element, echoing Season 1’s blend of crime and atmospheric tension.

The recast Naya Vasquez, whose new actor remains undisclosed, will continue as Kyle’s investigative partner, though fans worry about replicating the chemistry with Bana. The baby’s introduction adds a personal layer to the case, with the DNA test in Episode 4 likely triggering a chain of revelations that connect the child to the broader mystery. The return of the man Kyle thought was dead, possibly Paul Souter or another figure from his past, could further complicate the investigation, with the secret letter and the baby’s true parentage as key puzzle pieces.

Returning Cast and Evolving Stakes

Eric Bana returns as Kyle Turner, anchoring the series with his raw, emotionally charged performance. The recast Naya Vasquez remains a focal point of fan debate, with hopes that the new actor can match Lily Santiago’s intensity. Supporting characters like ISB colleagues or park staff may return, though the anthology format suggests new faces will dominate. The man Kyle thought was dead, potentially Paul Souter (Sam Neill), is a confirmed returnee, and his connection to the baby and the secret letter could drive the season’s conflict.

The DNA test’s fallout is expected to deepen Kyle’s arc, forcing him to confront betrayal, guilt, or a painful truth about his past. The five-year time jump places him in a darker headspace, with the baby initially offering hope of redemption before the devastating revelation. Fans speculate that the child’s true parentage might tie to Kyle’s son’s murder, a lingering trauma that continues to shape his journey.

Fan Reactions and Anticipation

The news of the baby and the DNA test has set social media ablaze, with X posts reflecting a mix of excitement and dread. One fan wrote, “A baby Kyle thought was his, then a DNA test in Episode 4? Untamed is coming for our hearts!” Another posted, “If the baby’s tied to Paul Souter or Kyle’s son, I’m not surviving this season.” The combination of the returning character, the secret letter, and now the DNA twist has fans bracing for an emotionally charged narrative, with one user noting, “October 3 can’t come soon enough. This is gonna destroy Kyle worse than Season 1.”

Critically, Season 1 was lauded for its “visually sumptuous” setting and Bana’s “steady star power” (Rotten Tomatoes), though some critiqued its pacing (The Guardian). Season 2 will need to balance its new mystery with Kyle’s personal turmoil, ensuring the baby and DNA test enhance rather than overshadow the investigative core. The anthology format and new park setting promise fresh visuals, while the emotional weight of the DNA revelation could elevate the series to new heights.

Countdown to October 3

With its October 3, 2025, premiere, Untamed Season 2 is poised to deliver a heart-wrenching and suspenseful chapter in Kyle Turner’s story. The revelation that the baby isn’t his, confirmed by a DNA test in Episode 4, sets the stage for a season of betrayal, mystery, and emotional devastation. As Kyle navigates a new national park and a fresh case, the return of a man from his past and a secret letter threaten to unravel his world, with the baby’s true parentage at the heart of it all.

Untamed Season 1 is streaming on Netflix. Stay tuned for updates on Season 2’s cast, trailer, and plot details.
