Netflix finally dropped the hammer on the reboot's second outing, and honestly, the collective gasp when Sean Milla was revealed as the saboteur could be heard across every Reddit thread dedicated to the show. It was a masterclass in hiding in plain sight. If you spent the whole season screaming at your TV because Ryan was acting "sus" or Muna was playing too hard, you weren't alone. But looking back at the wreckage of the pot, the answer to The Mole Season 2 who is the mole was always the retired undercover cop.
Talk about irony.
The guy literally spent his career pretending to be people he wasn't, yet we—and most of the contestants—bought the "clueless dad" act hook, line, and sinker. It’s wild.
The Big Reveal: Sean Milla Was the Saboteur
Let’s get into the nitty-gritty of that finale. Throughout the season, the prize pot was hemorrhaging cash. We saw $50,000 disappear here, a few thousand there. By the time host Ari Shapiro gathered the final three—Michael, Muna, and Sean—the tension was thick enough to cut with a dull knife.

When Sean stood up, it felt like a gut punch to Muna, who had played one of the most strategic games in the history of the franchise. Michael O'Brien, however, wasn't surprised. He had his sights set on Sean for a huge chunk of the game. That’s why Michael walked away with the $154,000. He realized that the guy claiming to be a "stay-at-home dad" was actually a highly trained manipulator.
Sean's "day job" was the ultimate cover. Most moles in the past (think back to the OG seasons with Anderson Cooper) tried to play the "I’m just here to help" card. Sean played the "I’m just struggling to keep up" card. It’s a subtle shift, but it’s devastatingly effective in a high-stress environment like The Mole.
How Sean Sabotaged the Game Without Anyone Noticing
Sean didn't just stumble into this. He was surgical.
Remember the gala mission? The one with the guests and the hidden clues? Sean was tasked with making sure the players didn't succeed, and he did it by simply being... "bad" at his job. He "accidentally" missed details that were right in front of him. In reality, he was redirecting the group's focus away from the actual solutions.
But his biggest move? The "Big Lie" about his career.
By telling everyone he was a stay-at-home dad, he lowered their defensive barriers. People don't expect a suburban father of kids to be a psychological mastermind. He used that bias. During the "Shipping Crates" mission, he managed to swap out information that cost the group $10,000. He did it with a smile and a shrug.

The Ryan Diversion
For a long time, the audience and the players were convinced it was Ryan. She was quiet. She was observant. She made a massive "mistake" during the cocktail party mission where she supposedly saw something that wasn't there.
Wait.
That was actually Sean’s brilliance. He clocked that Ryan was a person of interest and leaned into her mistakes. If someone else is acting weird, a good Mole just stays quiet and lets the paranoia do the work for them. Sean was the king of letting other people take the heat.
The Michael and Muna Dynamics
Muna was the heart of the season. She played loud. She took the exemptions. She made herself a target because she knew that in this game, if people think you’re the Mole, they fail the quiz. It’s a classic "Reverse Mole" strategy.
Michael, on the other hand, was a quiet observer. He caught Sean in a few lies early on—little inconsistencies about his "dad life" that didn't add up with his physical fitness and his tactical way of moving during missions. While Muna was busy being the loudest person in the room, Michael was taking mental notes on Sean’s footwork.

Sean Milla used a tactic often referred to in undercover work as "The Humble Idiot." If you pretend you don't understand the complex instructions of a mission, people will naturally step in to help you. They won't suspect you're sabotaging it; they'll just think you're incompetent.
In reality, Sean was calculating the exact moment to drop a hint or "lose" a piece of equipment. He was particularly good at the social game. He built genuine-ish bonds with players like Hannah and Tony, which made it emotionally difficult for them to vote against him in the quizzes.
The Strategy of the Final Quiz
The final quiz is a brutal 20-question gauntlet. You have to know everything: What did the Mole eat for breakfast? What color socks were they wearing during the heist? Which side of the bed do they sleep on?
Michael won because he stopped looking at the "obvious" saboteurs. He stopped looking at Muna's loud plays and started looking at Sean's quiet failures.
- The Weight of Evidence: Michael realized that whenever Sean was in a leadership role, the money stayed low.
- Tactical Observations: He noticed Sean's "undercover" habits—how he scanned rooms and kept his back to the wall.
- Consistency: Unlike others who flipped their suspicions, Michael doubled down on Sean.
The Legacy of Season 2
This season felt different from the first Netflix season. It was grittier. The locations in Malaysia were stunning, but the gameplay was much more cynical.
The Mole Season 2 who is the mole became a trending topic not just because of the mystery, but because the editing was actually fair. If you go back and re-watch (which you totally should), the clues are everywhere. There's a moment in the first episode where Sean's body language completely shifts when he thinks the camera isn't on him. It's chilling.
Sean proved that the best way to win The Mole—or rather, to be the best Mole—is to be the person everyone wants to grab a beer with at the end of the night. If they like you, they won't suspect you.
How to Spot the Mole in Future Seasons
If you're already gearing up for Season 3, take notes from Sean's playbook. Don't look for the person breaking things. Look for the person who is "accidentally" making things slightly harder for everyone else.
- Watch the eyes. Sean was always looking at the producers or the perimeter, not the prize.
- Follow the money. Who was present for every single "unfortunate" loss of cash? It was almost always Sean.
- Ignore the "Sus" edits. The editors love to make the winner look like the Mole to keep you guessing. Muna was the classic "red herring."
- Listen to the background stories. If someone’s story feels a little too "cookie-cutter"—like a retired cop pretending to be a stay-at-home dad—they're probably lying about more than just their job.
Honestly, Sean Milla might be one of the top three Moles of all time. He played a clean, psychological game that left even the smartest players (sorry, Muna) scratching their heads in the finale. Michael's win was hard-earned, but Sean’s performance was the real star of the show.
If you want to sharpen your own detective skills, go back to episode 3 and watch Sean during the forest trek. Now that you know he's the Mole, his "struggles" look a lot more like calculated delays. It changes the whole vibe of the season.
Next Steps for Fans:
- Re-watch the finale specifically to see Sean's post-reveal interview where he breaks down his specific sabotages.
- Check out the "Mole" subreddit for the frame-by-frame breakdown of the "clues" Netflix hid in the intro credits (yes, they were there).
- Compare Sean’s gameplay to Kesi from Season 1 to see how the "Incompetence vs. Aggressive Sabotage" strategies differ.
The game is over, the money is won, and Sean Milla can finally stop pretending he doesn't know how to read a map. But for the rest of us, the hunt for the next great saboteur has already begun.
