What Really Happened in Unfamiliar Episode 6 (Full Spoilers)

Full spoilers ahead for Unfamiliar (Netflix), Episode 6 (“Still Alive”). If you haven’t finished the finale, stop here—because everything below breaks down the last twists scene-by-scene, including who “Starfish” really is, what becomes of Josef Koleev, and why Katya walks away with Nina.

Unfamiliar looks like a standard “retired spies get pulled back in” thriller—until the finale makes one thing painfully clear: the real weapon isn’t a gun or a tracker bullet. It’s the decade-plus of lies holding the Schäfer family together.

Quick refresher: who’s who going into the finale

  • Meret Schäfer: ex-BND agent, co-runs “The Nest” safe house, fiercely protective, running out of patience for secrets.
  • Simon Schäfer: ex-BND agent, co-runs the safe house, hiding both a medical crisis and the origin story of Nina.
  • Nina: their 16-year-old daughter, finally demanding the truth.
  • Katya: the woman tied to the Belarus operation—and the person with the strongest claim to Nina.
  • Josef Koleev: Russian power player connected to the past mission; the immediate threat closing in.
  • Julika: BND agent trying to untangle the mole situation while keeping Nina alive.
  • Ben: Julika’s boss at the BND… who turns out to be much more than a boss.
  • Vera: Josef’s wife, newly elevated politically, no longer willing to be collateral damage.
  • Jonas Auken: a key operator in Josef’s orbit, suddenly not acting like a simple hired gun.

Episode 6 recap (what happens, in order)

The finale begins with Meret and Simon realizing Josef is about to hit their location hard. Their plan is simple and brutal: hold the line in their high-tech safe house long enough to get Nina out alive. But Nina refuses to leave without answers—so they give her a flash drive meant to explain at least part of the truth.

Downstairs, Nina watches a recorded message from her parents explaining their BND past—just as the building is being swept by Josef’s people. The safe house turns into a trap: doors, lights, and locks become weapons, and Meret and Simon fight like two people who’ve done this before… even while their marriage is actively collapsing.

Then comes the first “wait, what?” moment: a note is slipped under their door that essentially signals help from inside the enemy’s operation—setting up the reveal that not everyone on Josef’s side is there voluntarily.

At the same time, Vera confronts Josef about the Belarus truth. Josef tries to frame himself as a man “fixing” the past, but Vera is done buying his version of events—especially with her own political future now on the line.

The shootout escalates, and the episode makes a sharp pivot: Jonas isn’t just a villain-of-the-week. He’s negotiating survival, playing both sides, and trying to cash out of Josef’s control. Josef responds the way Josef always responds: with lethal certainty. Jonas is killed, and the safe house battle ends with Meret dragging an unconscious Simon out—because Simon’s untreated aneurysm finally catches up with him mid-chaos.

They make it to the hospital. Simon survives surgery. But the family doesn’t survive the night in the same form.

The ending explained: the 6 biggest reveals in Episode 6

1) Jonas wasn’t “switching sides” for love—he was trying to stop being owned

The note under the door and Jonas’s behavior point to something the series keeps repeating: everyone in this story is trapped by someone else’s leverage. Jonas’s “help” reads less like a redemption arc and more like a last attempt to escape Josef’s orbit without being erased. Josef choosing to kill him is the show’s reminder that Josef does not allow exits—only endings.

2) Simon’s aneurysm is the finale’s cruelty engine

On paper, the safe house should give Meret and Simon an advantage: it’s built for containment and control. But Simon’s health turns every clever defensive move into borrowed time. The finale uses the aneurysm the way a great thriller uses a ticking bomb—except the “bomb” is inside the family, and it’s been ignored for too long.

3) “Starfish” is revealed—and it detonates the BND storyline

The mole isn’t a random traitor hiding in a back office. The finale’s reveal reframes the entire BND plot as top-down rot: Ben is Starfish. Even worse, the show positions him as someone who can’t simply “quit” the role once exposed—because Vera records/leverages his confession to keep him useful.

4) Josef’s fate: removed as a piece, not defeated as a system

By the end, Josef is no longer a free-moving threat in Berlin. He’s brought to heel through Vera and her father’s machinery, and the show implies he’s being eliminated (or at least neutralized) off-screen. That’s an important distinction: Meret and Simon don’t truly beat Josef. The Russian apparatus simply decides he’s become inconvenient.

5) Simon and Meret choose separation—and it’s not framed as a twist

The finale doesn’t ask “will they stay together?” as a romantic cliffhanger. It treats the marriage like an exhausted cover identity that’s finally failing. Simon admits the scale of what he did to “save” them, and Meret’s reaction isn’t a shock—it’s grief. The emotional logic is: you can’t build a family on a stolen truth and expect it to hold under gunfire.

6) Katya takes Nina… with BND help

The final betrayal is clean and surgical. Katya doesn’t grab Nina during a firefight; she moves her at the hospital, when everyone is disoriented and emotionally wrecked. She positions it as protection (“Josef is still coming”), gets Nina moving, and hands her off into an escape route involving Julika’s car.

And then the gut punch: Meret and Simon are arrested and pinned for Jonas’s murder. Katya leaves with Nina, while Meret watches the car pull away—too late to stop it, too cornered to chase it.

Why Katya really did it (the motive underneath the betrayal)

Katya’s decision plays on two levels at once:

  • Maternal logic: Nina is demonstrably unsafe around Simon and Meret, not because they don’t love her, but because their past creates an endless blast radius.
  • Power logic: Katya needs institutional protection. The BND will only pay that price if she gives them something valuable. Handing them Meret and Simon (and a tidy “Jonas murder” narrative) is the currency.

That’s what makes the finale sting: Katya doesn’t have to be purely evil to do something unforgivable. The show frames her as someone choosing the move that works, not the move that heals.

What Reddit Theories Say About this

Unfamiliar (Netflix) has that Slow Horses vibe.
by u/ in r/SlowHorses

One of the more useful Reddit angles isn’t “who’s secretly alive?”—it’s tone. Viewers comparing Unfamiliar to other spy series often land on the same point: the action is fun, but the real hook is watching institutions and relationships grind people down.

Unfamiliar hat gut angefangen und stark nachgelassen
by u/ in r/Filme

Another recurring Reddit-style critique is realism: if Meret and Simon are truly elite ex-agents, why do they keep getting outplayed socially and institutionally? Episode 6’s answer is harsh: tradecraft can’t save you from leverage, and the biggest leverage in the show is Nina.

Unanswered questions (and what a Season 2 would need to resolve)

  • Where is Nina going—right now? Katya’s escape is the final image, but her long-term plan (and who’s backing it) is still unclear.
  • Is Ben acting under blackmail, ideology, greed, or fear? The reveal “Ben is Starfish” is a beginning, not a conclusion.
  • How much does Julika know about Katya’s true endgame? Julika helps facilitate the exit route, but that doesn’t mean she controls it.
  • Can Meret and Simon clear the Jonas charge? The arrest is more than a cliffhanger; it’s a mechanism to remove them from Nina’s life.
  • What’s the real cost of the Belarus lie becoming public? The finale shows consequences, but the political blast radius is still loading.

FAQ

Who is Starfish in Unfamiliar?

Starfish is the mole inside the BND. Episode 6 reveals Starfish is Ben, Julika’s boss, and he’s immediately pulled into a new leash of blackmail and leverage.

Does Josef die in Episode 6?

Episode 6 strongly implies Josef is “handled” by Vera’s side of the Russian power structure. The show treats his removal as an off-screen political execution/neutralization rather than a heroic kill.

Why did Katya take Nina?

Because Nina is the center of the entire conflict: she’s the reason Meret and Simon ran, the reason Josef returned, and the only bargaining chip big enough to buy protection. Katya chooses control and safety over consent and healing.

Why are Meret and Simon arrested?

They become convenient scapegoats for Jonas’s death—while the BND’s internal corruption problem remains active. The arrest also functionally removes them from Nina’s immediate reach.
