Ginny & Georgia Season 4 Finally Answers the Biggest Question: “Is Zion Really Ginny’s Biological Father?” — And the DNA Test Scene Is Jaw-Dropping

The Netflix dramedy Ginny & Georgia has kept fans hooked with its whirlwind of family secrets, love triangles, and shocking twists since its debut in 2021. Season 3, which premiered on June 5, 2025, left viewers reeling with Georgia’s surprise pregnancy and a lingering question about Zion Miller’s (Nathan Mitchell) role as Ginny’s (Antonia Gentry) biological father. Now, a teaser for Season 4, slated for release in mid-2026, has confirmed that the show will finally address the long-standing fan theory: Is Zion really Ginny’s biological father? The jaw-dropping DNA test scene teased by the cast and creators has sent fans into a frenzy on social media. Here’s everything we know about this pivotal moment, the Season 4 release, and what it means for the Miller family.

The Teaser That Shook Wellsbury

On June 10, 2025, Netflix dropped a cryptic 45-second teaser for Ginny & Georgia Season 4 on its official social media channels, igniting speculation about the show’s biggest mystery. The teaser opens with Ginny sitting in her therapist’s office, visibly nervous, clutching a sealed envelope. The camera pans to Zion, who looks equally tense, as Dr. Lily (Zarrin Darnell-Martin) gently asks, “Are you ready to know the truth?” The scene cuts to Georgia (Brianne Howey) pacing outside, muttering, “This changes everything.” The teaser ends with Ginny tearing open the envelope, her eyes widening, and a voiceover saying, “Some secrets can’t stay buried.” The screen fades to black, leaving fans desperate for answers.

The DNA test scene has been a long time coming, fueled by fan theories that have circulated since Season 1. Zion, introduced as Ginny’s free-spirited photographer father, has been a constant presence in her life, but Georgia’s murky past and history of manipulation have led some to question whether he’s truly her biological father. The Season 4 teaser confirms that this question will be answered, and the emotional stakes are higher than ever.

Season 4 Release Date and Production Updates

Netflix has confirmed that Ginny & Georgia Season 4 will premiere in mid-2026, likely between June and July, following the show’s pattern of roughly annual releases. Production began in February 2025, with creator Sarah Lampert sharing an Instagram post captioned, “First day of the Season 4 writer’s room!!! Based on today alone, Season 4 is going to be a RIDE.” Filming is underway in Toronto, with Brianne Howey and Antonia Gentry spotted on set in early June 2025. The accelerated timeline suggests Netflix is eager to capitalize on the show’s massive popularity, with Season 3 drawing 17.6 million viewers in its first week, landing at No. 1 on Netflix’s Top 10.

The Season 4 theme, “Cycles and Origins,” hints at a deep dive into Georgia’s past, including her abusive childhood and estranged family. The DNA test scene is poised to be a cornerstone of this exploration, potentially reshaping the Miller family dynamic. Lampert told Tudum, “We’re peeling back layers of truth about who these characters are and where they come from. It’s messy, but it’s real.”

The Zion Paternity Question: Why It Matters

The question of whether Zion is Ginny’s biological father has been a fan obsession since Season 1, when flashbacks revealed Georgia and Zion’s whirlwind teenage romance. The two met when Georgia, then a runaway teen, crossed paths with Zion during his gap-year road trip. Their crime-fueled love story led to Georgia’s pregnancy with Ginny, but Zion’s absence during much of her childhood—due to Georgia’s decision to raise her alone—has raised doubts. Georgia’s history of lying, including faking a pregnancy in Season 3, has only fueled speculation that she might have hidden the truth about Ginny’s paternity.

Season 3 deepened the intrigue by showing Zion stepping up as a father, petitioning for joint custody and taking Ginny on a summer trip to South Korea. His evolving bond with Ginny, coupled with his strained relationship with Georgia after her murder trial, has made the paternity question even more urgent. Fans on X have theorized wildly, with one user posting, “If Zion’s not Ginny’s dad, I’m done. That’s too much for her to handle! #GinnyAndGeorgia.” Another wrote, “Georgia’s secrets are endless—what if Zion’s been lied to this whole time?”

The teaser’s DNA test scene suggests a definitive answer is coming. Nathan Mitchell, who plays Zion, teased in a June 2025 interview with TODAY.com, “This moment is a turning point for Zion and Ginny. It’s raw, it’s real, and it’s going to hit hard.”

What the DNA Test Scene Could Mean

While the teaser doesn’t reveal the results, the emotional weight of the scene is palpable. The setting in Dr. Lily’s office suggests that the paternity question will be addressed with the support of therapy, reflecting Ginny’s ongoing journey to process her trauma. The presence of Georgia outside, visibly anxious, hints that the results could challenge her control over the family narrative. Showrunner Sarah Glinski told Deadline, “The DNA test isn’t just about biology—it’s about trust, identity, and what makes a family. Ginny’s been through so much, and this is her reckoning.”

Fan theories range from Zion being confirmed as Ginny’s father, solidifying their bond, to a shocking reveal that someone else—perhaps a figure from Georgia’s past, like her abusive stepfather or a mystery character—is her biological father. The latter would align with Season 4’s “Origins” theme, potentially tying into Georgia’s mother and stepfather tracking her down in Wellsbury, as seen in Season 3’s finale.

The DNA test could also impact Georgia’s pregnancy cliffhanger from Season 3, where she’s unsure whether Paul (Scott Porter) or Joe (Raymond Ablack) is the father of her unborn child. Lampert confirmed to TVLine that the writers have decided on the baby’s paternity but remain open to changes, suggesting parallel paternity dramas for mother and daughter.

Fan Reactions and Speculation

The teaser has sparked a firestorm of reactions on X, with fans divided over what they hope the DNA test reveals. One user posted, “Zion HAS to be Ginny’s dad—his love for her is too real to be fake! #ProtectGinny.” Another speculated, “What if Georgia lied to protect Ginny from someone dangerous? The stepdad vibes are creepy.” The emotional intensity of the teaser, combined with the cast’s cryptic comments, has fans bracing for a heartbreaking or empowering moment.

Antonia Gentry, who plays Ginny, told Tudum, “Ginny’s becoming her own person, but she’s also becoming her mother. This season, she faces the truth head-on, and it’s both freeing and terrifying.” The parallel between Ginny’s paternity question and Georgia’s pregnancy underscores the show’s theme of mirrors between mother and daughter.

New and Returning Faces in Season 4

Season 4 will see the return of core cast members, including Brianne Howey as Georgia, Antonia Gentry as Ginny, Diesel La Torraca as Austin, and Nathan Mitchell as Zion. New characters will include Georgia’s mother and stepfather, whose arrival in Wellsbury promises to unearth painful memories. Lampert teased to Tudum, “Meeting Georgia’s family is going to flip everything upside down. It’s not just about the past—it’s about how it shapes the future.”

Zion’s girlfriend, Simone (Vinessa Antoine), will also play a larger role, potentially navigating the fallout of the DNA test. Meanwhile, Ginny’s love life, including her complicated relationship with Marcus (Felix Mallard), who’s in rehab after Season 3, will continue to evolve.

The Bigger Picture for Ginny & Georgia

Ginny & Georgia remains a Netflix powerhouse, with Season 3 racking up 504.77 million hours watched globally in its first 28 days. The show’s blend of drama, humor, and heart has made it a fan favorite, and Season 4’s focus on “Cycles and Origins” promises to deepen its emotional impact. For fans craving similar vibes, Netflix recommends Firefly Lane, a mother-daughter drama with a focus on friendship and secrets.

The DNA test scene is poised to be a defining moment for Ginny, Zion, and Georgia, forcing them to confront the truth about their family. Whether Zion is confirmed as Ginny’s father or a shocking twist upends everything, the fallout will reshape their relationships. As Lampert told Entertainment Weekly, “We’ve known this question was coming since Season 1. The answer is going to break hearts and maybe heal some too.”

Looking Ahead

With Ginny & Georgia Season 4 set to premiere in mid-2026, fans can stream Seasons 1–3 on Netflix to catch up on the drama. The DNA test scene, teased as a jaw-dropping moment, will answer the biggest question about Zion’s paternity while setting the stage for new conflicts. Will Ginny’s bond with Zion survive the truth? Can Georgia face her past without losing her family? One thing’s certain: Wellsbury’s secrets are about to unravel, and the Miller family will never be the same.
