Spoiler alert! The following contains details from the Season 2 premiere of "High Potential" on ABC.

Morgan (Kaitlin Olson) may be the smartest person in the room, but there are some mysteries and problems she can't solve.

The quirky, irreverent police consultant has started to realize that in ABC's "High Potential" (Tuesdays, 10 ET/PT), which just returned with a shocking Season 2 premiere that solves one mystery while creating quite a few more. It's an exciting start for the police procedural, a standout among new shows last year on network TV, and a faux-fur-fringed showcase for the "It's Always Sunny in Philadelphia" star.

Here's what you need to know from the tense and eventful premiere episode.

The Game Maker ups the stakes, then turns himself in

When we last left Morgan at the end of Season 1, she and her police detective partner Adam Karadec (Daniel Sunjata) were chasing a serial kidnapper known as "The Game Maker," who left a maliciously playful trail of clues for investigators to follow. The logic puzzles seemed tailor-made for someone like Morgan, a high-IQ intellectual who consults with the police and notices things others miss.

In the Season 1 finale, the Game Maker seemed to be two steps ahead of Morgan and Adam, and even kidnapped their beloved coworker Detective Lev Osman (Deniz Akdeniz), horrifyingly leaving him trapped at the bottom of a pool. They barely got Oz back before Morgan encounters a slick and charming stranger in the grocery store parking lot with her kids, who slips a Game Maker-marked card game into her shopping bag.

With this brush with a violent predator, the Season 1 premiere finds Morgan sheltering in place at home with her kids and her ex Ludo (Taran Killam) while a police officer watches over the house outside. It seems like maybe the Game Maker isn't interested in her anymore, but then she receives a piece of mail meant for a neighbor. It leads her to a house of a woman who has been abducted in the last 24 hours, another blond single mom.

Although all signs point to the woman's lecherous boss as her kidnapper, Morgan is convinced the Game Maker is ultimately behind the crime. Eventually she and the squad find evidence of the serial kidnapper's involvement, but not before other people are in danger and the man Morgan met in the parking lot shows up at the police station, turning himself in to Morgan and Lieutenant Selena Soto (Judy Reyes), all the while with a creepy smile on his face.

Is this good-looking charmer really the Game Maker? And where is the poor single mother he kidnapped? The premiere ends before we get more answers.

Did Morgan find her missing lover Roman in the 'High Potential' premiere?

There's another mystery plaguing Morgan and her family in the Season 2 premiere. Throughout the first season, Morgan, Soto and Karadec have been searching for Morgan's ex Roman, the father of her eldest daughter. Roman disappeared one day while out buying diapers, and at the end of Season 1 Karadec calls Morgan with the news that he may have found Roman.

In Season 1 Morgan discovered Roman may have inadvertently become involved in Los Angeles' criminal underworld, and Karadec finds out Roman was an FBI informant who's likely now in Nevada. In the Season 2 premiere, the local police calls with an address, but Morgan can't leave her kids while the Game Maker is still a threat, so Oz and their fellow officer Daphne Forrester (Javicia Leslie) make the road trip to the motel where Roman is supposedly living.

Before they find out who is behind that mysterious door, the camera cuts to a man in a motel room. He pulls an envelope out from underneath a mattress with that same address written inside. The camera pans up and its actor Mekhi Phifer, known for shows like NBC's "ER" and Apple TV+'s "Truth Be Told."

Is that Roman? Is he in the motel room Oz and Daphne are about to enter? And if it is Roman, why is he safe and sound and ignoring Morgan and his daughter? What will he say when confronted by the police?

It doesn't take a genius to see Morgan has plenty to deal with for the rest of Season 2.
