Premiering its second season on September 16, 2025, the series—adapted from the acclaimed French-Belgian show HPI (Haut Potentiel Intellectuel)—quickly became a ratings juggernaut. After a strong first season that drew massive multi-platform viewership (peaking at over 11 million for the premiere across ABC, Hulu, and Disney+), Season 2 expanded to 18 episodes, allowing for richer character development and more intricate plotting. The show returned from hiatus on January 6, 2026, picking up right where it left off, and fans have been buzzing ever since.

At the heart of the series is Morgan Gillory (Olson), a single mother of three with a staggering IQ of 160. Once a cleaner at the LAPD, her extraordinary pattern-recognition skills landed her a consulting role in the Major Crimes Division. Season 2 dives deeper into Morgan’s chaotic personal life while she tackles increasingly complex cases alongside her reluctant partner, Detective Adam Karadec (Daniel Sunjata). The dynamic between the free-spirited Morgan and the by-the-book Karadec remains a highlight—described by Olson as a “slow burn” that evolves organically amid high-stakes investigations.

High Potential’ Showrunner On “Answers To Big Questions” In Season 2

The serialized mystery surrounding Morgan’s ex-husband Roman’s 15-year disappearance intensifies this season. Season 1’s finale revealed Roman is alive, setting up tantalizing questions: Why did he vanish? What secrets does he hold? New recurring players, including Mekhi Phifer as Arthur Ellis (a man claiming ties to Roman) and Susan Kelechi Watson in a yet-to-be-detailed role, add layers of intrigue. Meanwhile, the shadowy “Game Maker”—a serial threat from Season 1—continues to loom, targeting Morgan’s family and forcing her to confront vulnerabilities she rarely shows.

Off the clock, Morgan navigates relatable family chaos. Her daughter Ava (Amirah J) deals with teenage social pressures, while sons Elliot (Matthew Lamb) and others bring warmth and humor. These domestic threads ground the high-octane crime-solving, making Morgan’s genius feel human and flawed. Kaitlin Olson, known for her sharp comedic timing from It’s Always Sunny in Philadelphia, infuses Morgan with wit, vulnerability, and edge. She has teased that Season 2 delivers “really fun, dramatic moments,” blending heartfelt storytelling with her signature comedic flair.

The ensemble shines brightly. Daniel Sunjata’s Karadec provides steady contrast to Olson’s chaos, while Judy Reyes as Lieutenant Selena Soto anchors the team with authority and depth.

Critically, Season 2 has earned rave reviews, boasting a perfect 100% on Rotten Tomatoes from early episodes and a solid 75/100 on Metacritic.
