A shocking reversal leaves Tamar exposed
Season 3 of Tehran has just delivered one of its most brutal turns. Tamar (Niv Sultan), who has spent the series walking a razor’s edge between loyalty and survival, is forced to confront the cost of misplaced trust after a startling betrayal by her newest ally, nuclear scientist Eric Peterson (Hugh Laurie). What began as a fragile partnership aimed at exposing Iran’s weapons program collapses when Peterson disarms Tamar, holds her at gunpoint and — as the show makes clear — is the one who tipped off the Sepah. That revelation leaves Tamar isolated, hunted and more vulnerable than ever.
What we saw — and what’s at stake
The fallout of Peterson’s treachery plays out immediately in the lead-up to Episode 6. An explosive shootout gives Tamar a narrow escape from Peterson’s immediate threat, but the victory is pyrrhic. Waiting nearby is Faraz Kamali (Shaun Toub), who has long vowed to eliminate her. Tamar tries to flee with Nissan (Sasson Gobai) but not before Peterson fires on her, leaving her wounded and scrambling for safety deep inside Tehran — where one wrong step can mean death.
This sequence sharpens two recurring Tehran themes: the precariousness of alliances in espionage, and the extreme physical and moral dangers Tamar faces while operating undercover in the city she once called home.
Why Peterson’s betrayal matters
Peterson’s flip is significant for several reasons:
- It removes one of Tamar’s few high-level allies at a moment when she needs them most.
- It reframes the scientist’s motives — was he turned, coerced, or strategically playing both sides? The show leaves room for interpretation, increasing narrative tension.
- It exposes Tamar’s vulnerability. After going rogue in Season 2 and being marked by her own agency, Tamar has been trying to reinvent herself and regain the Mossad’s trust. Losing Peterson forces her to navigate hostile territory with fewer resources and fewer safe options.
The revelation that Peterson alerted the Sepah — a shorthand reference within the series to Iran’s Islamic Revolutionary Guard Corps — raises the stakes for every character whose fate hinges on whether secrets stay secret.
Tamar’s arc this season: reinvention under fire
Created by Dana Eden, Maor Kohn and Moshe Zonder, Tehran has consistently pushed its heroine into impossible situations: undercover work in her hometown, operations that imperil loved ones, and repeated confrontations with both the Mossad and Iranian security forces. Season 3 continues that pattern but foregrounds survival as a central concern. After defying orders at the end of Season 2, Tamar’s survival strategy has been twofold: reinvent herself to blend back into Tehran’s dangerous landscape, and find a path back into the Mossad’s good graces.
That effort has been complicated by shifting loyalties and the arrival of new players. With Peterson’s betrayal and Kamali’s relentless pursuit, the season is tightening around Tamar, forcing increasingly risky choices and raising questions about whom she can trust — and whether trust is even possible in her world.
New and returning faces amplify the tension
Season 3 brings both familiar faces and notable newcomers. Niv Sultan and Shaun Toub remain central, and the season has welcomed back Shila Ommi to the main cast. Joining them are Hugh Laurie as Eric Peterson and additions credited as Gabbai, Phoenix Raei and Bahar Pars, each adding layers to the series’ international intrigue.
The show has a history of high-profile guest turns that amplify its stakes: Season 2 included a memorable appearance by Glenn Close as a British Mossad agent. Laurie’s casting continues that tradition of leveraging well-known talent to deepen the series’ moral and dramatic complexity.
Reception and renewal — the saga continues
Critics and audiences have responded positively to Tehran’s third season, with strong reviews reflecting appreciation for its tense plotting and character work. Apple TV has already secured a fourth season, ensuring the story will continue to evolve as Tamar’s choices reverberate.
When to watch and what to expect next
Episode 6 of Tehran Season 3 premieres on Apple TV on February 13. Collider has released an exclusive sneak peek that picks up directly after the betrayal and sets the tone for the coming episodes: high stakes, fractured alliances and a protagonist pushed to her limits.
Expect the next episodes to deepen the mystery around Peterson’s motives, escalate the chase led by Faraz Kamali, and force Tamar into even riskier gambits as she fights not just to survive, but to decide what kind of future is possible after so much loss.
