She’s back. Morgane Alvaro, the cleaning lady with a 160 IQ and a wardrobe that looks like a neon fever dream, hasn't lost her touch. If you’ve been following the French phenomenon HPI (Haut Potentiel Intellectuel), you know the drill. It’s loud. It’s messy. It’s brilliant. But HPI Season 4 hits differently because, for the first time, Morgane can’t just "think" her way out of the problem.
She’s pregnant.
That’s the bombshell the writers dropped. And honestly, it changes the entire chemistry of the show. We’ve watched Audrey Fleurot play this character with a mix of exhaustion and manic energy for three years, but this season forces her to face a reality where her brain isn't the only thing running at a million miles per hour.
Why the HPI Season 4 Premiere Left Us Reeling
The first episode doesn’t waste time. We pick up exactly where that messy Season 3 finale left us. Morgane is staring at a positive pregnancy test, and in typical Morgane fashion, she’s not exactly handling it with grace.
But here is the real kicker: she has no idea who the father is.
It’s a three-way toss-up. Is it Timothée? David? Or Karadec? Fans have been screaming for the Morgane and Karadec (Mehdi Nebbou) "ship" to finally sail, but after that tension-filled hookup, things are... awkward. To put it mildly. Karadec is trying to move on, and Morgane is, well, Morgane. She’s hiding the pregnancy while simultaneously trying to solve a murder involving a woman found dead in a high-tech smart home.
The contrast is hilarious. You have this hyper-logical crime scene and this woman whose personal life is a literal dumpster fire.

The Evolution of the High Intellectual Potential
One thing people often get wrong about HPI is thinking it's just another "Sherlock" clone. It isn't. Sherlock is cold. Morgane is boiling over. In HPI Season 4, the show explores what happens when a person with a high intellectual potential (HPI) loses their sense of control.
High-IQ individuals often struggle with sensory overload. Add pregnancy hormones to that? It’s a recipe for disaster. The writers, including Alice Chegaray-Breugnot, have been very careful to keep the procedural elements tight while letting the character drama go completely off the rails. It’s a delicate balance. If the cases were boring, we’d check out. If the drama was too heavy, it wouldn’t be HPI.
Fortunately, the cases this season—ranging from a mysterious death in a retro-gaming bar to a complex kidnapping—are as sharp as ever.
The Karadec Problem
Let’s talk about Karadec. Poor Adam Karadec.
The man just wants to do his job. He wants rules. He wants a quiet life. And then there’s Morgane. In HPI Season 4, their dynamic shifts from "will-they-won't-they" to something much more complicated and, frankly, painful. Karadec is still reeling from the fallout of their night together. He’s hurt. He feels used.
When he eventually finds out about the pregnancy (and yes, it happens in a way that is both cringe-worthy and heartbreaking), the tension reaches a breaking point. Mehdi Nebbou plays the "straight man" to Fleurot’s chaos so well that you almost forget he’s an actor. You just feel bad for the guy.

But that's the brilliance of the show. It doesn't give you the easy rom-com win. It makes you work for it.
Production and Global Success
Did you know HPI is one of the most-watched French series in the world? It’s been sold to over 100 territories. There’s even an American remake called High Potential starring Kaitlin Olson.
But let’s be real. Nobody does it like Audrey Fleurot.
The production value in Season 4 has clearly stepped up. The "flash" sequences—where we see inside Morgane’s brain as she connects the dots—are more stylized and inventive. The color palette is still aggressive, but there’s a maturity to the cinematography this year that reflects the higher stakes.
What to Expect in the Second Half of the Season
In France, TF1 decided to split the season. This drove fans crazy. We got the first four episodes, and then a long wait for the final four. If you are watching on streaming platforms outside of France, you might get them all at once, which is definitely the superior way to experience this rollercoaster.
The back half of HPI Season 4 focuses heavily on the paternity mystery. Morgane actually has to interact with her potential "baby daddies" in ways she never expected.

- Timothée: He’s sweet, but is he ready for Morgane-level drama?
- David: The "bad boy" energy is still there, but is it sustainable?
- Karadec: The obvious choice, but the one with the most emotional baggage.
Watching Morgane navigate doctor appointments while interrogating suspects is peak television. There's a scene in a later episode involving a sonogram that is genuinely one of the funniest things the show has ever done. It involves Morgane deducing a medical secret about the technician while she's supposed to be looking at her own baby. Classic.
Real-World HPI Traits
The show actually gets some things right about neurodivergence. People with high intellectual potential often feel "out of sync" with the world. They notice the things others ignore—the hum of a refrigerator, the slight twitch in someone’s eye when they lie, the pattern in a carpet.
Season 4 dives deeper into Morgane’s vulnerability. Her IQ is a superpower at work, but it’s a burden in her personal life. She can see exactly how she’s ruining her relationships, but she can’t always stop herself. It’s that self-awareness that makes her human.
Actionable Steps for Fans and Newcomers
If you are just catching up or waiting for the next batch of episodes, here is how to get the most out of the HPI Season 4 experience:
- Watch the Original: If you’ve only seen the trailers for the US remake, go back to the French original. The chemistry between the cast is lightning in a bottle.
- Pay Attention to the Background: The set designers hide clues in Morgane’s house and the precinct. Often, a visual gag in the background hints at the solution to the mystery.
- Track the "Morgane-isms": Part of the fun is seeing how many times she breaks police protocol. In Season 4, she sets a new record.
- Check Local Listings: Depending on your region (Disney+, Hulu, or local networks like TF1 or RTBF), the release schedule varies. Ensure you are looking at the 2024-2025 release window to avoid spoilers from earlier seasons.
The beauty of this show is its refusal to be "normal." It’s a procedural that hates procedures. It’s a comedy that occasionally punches you in the gut with real emotion. As we move toward the finale of Season 4, one thing is certain: Morgane Alvaro isn't going to have a quiet labor.
The impact of this season on the future of the series is massive. With a fifth season already in discussion, the resolution of the paternity mystery isn't just a plot point—it's the foundation for the next chapter of Morgane’s chaotic life. Brace yourselves, because the final episodes of this season are designed to leave you breathless.
