You probably felt that pit in your stomach during the season 3 premiere. We all did. Seeing the cast Criminal Minds Evolution without a certain detective felt like a glitch in the Matrix. For sixteen years, Will LaMontagne Jr. was the steady heartbeat outside the BAU. Then, just like that, he was gone.
The shift in the ensemble hasn't just been about who’s on the call sheet; it’s about how the show’s DNA is mutating. Transitioning from a broadcast procedural to a prestige streaming thriller on Paramount+ meant some beloved faces had to get left in the rearview mirror. Honestly, it’s been a messy, heartbreaking, and occasionally thrilling ride.
The Josh Stewart Exit That Nobody Saw Coming
Let’s be real: Josh Stewart’s departure was a gut punch. Fans were already on edge after that vague cancer scare in the first revival season. When Stewart took to X (formerly Twitter) to tell a fan his "days of playing Will LaMontagne Jr. are over," the internet basically melted down.

Season 3 didn't pull any punches. They killed him off. It wasn't some heroic shootout or a long-drawn-out illness, either. It was a sudden, devastating aneurysm. What’s wild is that Stewart didn't even come back to film the death scene. The showrunners actually had to dig into the archives and use deleted footage from the first season of Evolution to piece together his final moments.
It felt a bit disjointed, didn't it? One minute JJ (A.J. Cook) is balancing a career and a marriage, and the next, she’s a grieving widow. This massive change in the cast Criminal Minds Evolution serves a darker purpose, though. It strips away the safety net. In the original run, the BAU members had homes to return to. Now? The BAU is all they have left.
Matthew Gray Gubler: The Guest Star We Waited For
If you screamed when Spencer Reid finally walked onto the screen in season 3, you weren't alone. We’ve been hearing "scheduling conflicts" as an excuse for years. It started feeling like a polite way of saying "never going to happen."
But then came the episode Time to Say Goodbye.
Reid showed up at Will’s funeral. It was brief. It was quiet. He didn't come back with a briefcase ready to profile a new UnSub; he came back as a friend. Seeing him standing at the graveside with JJ was the closure we didn't know we needed.
"I’ll always show for you guys." — Dr. Spencer Reid

That line felt like it was directed at the audience as much as the characters. While Gubler is busy with his new CBS show Einstein (slated for the 2026-2027 season), this cameo proved the door isn't locked. It’s just... slightly ajar.
The New Guard and the Resident Monster
With the old guard shifting, the show had to fill the vacuum. Enter Ryan-James Hatanaka as Tyler Green. He’s the wildcard the BAU never really had before—someone who doesn't play by the FBI handbook. His promotion to a series regular changed the chemistry of the room. He’s messy, he’s vengeful, and he’s remarkably good at getting under everyone’s skin.
Then there’s Zach Gilford as Elias Voit.
Most shows would have killed off a season-long villain and moved on. Instead, Gilford has become the dark sun that the entire cast Criminal Minds Evolution revolves around. By season 3, Voit isn't just a prisoner; he’s a consultant, a manipulator, and a weirdly necessary evil. Watching him trade barbs with Joe Mantegna’s David Rossi is arguably the best part of the revival. Rossi is aging, he’s tired, and he’s haunted. Voit knows exactly which buttons to press to keep those ghosts alive.
A Different Kind of BAU
The current core team—Prentiss, Rossi, JJ, Garcia, Luke, and Tara—feels more like a family in crisis than a government unit.
- Paget Brewster (Emily Prentiss): She’s no longer just the boss; she’s a woman fighting a bureaucracy that wants the BAU dead.
- Aisha Tyler (Dr. Tara Lewis): Her personal stakes skyrocketed with the introduction of Rebecca Wilson (Nicole Pacent), proving that even the profilers aren't immune to messy breakups.
- Adam Rodriguez (Luke Alvez): He’s stepped into the "muscle with a heart" role, often acting as the bridge between Garcia’s tech world and the grit of the field.
Adding Felicity Huffman as Dr. Jill Gideon—the ex-wife of the late Jason Gideon—was a stroke of genius. It brought the show’s history back into the present without feeling like a cheap gimmick. She’s a "biological psychiatrist" who hates the BAU, which provides a fantastic friction against Rossi’s old-school profiling methods.
What This Evolution Means for You
The show isn't the comfort food it used to be. It’s leaner, meaner, and way more serialized. If you’re looking for the "case of the week" where everything is wrapped up in 42 minutes, those days are gone.
What you should do next:
- Watch for the subtle clues: The showrunners are leaning heavily into the "Gold Star" and "Sicarius" lore. Every interaction Voit has with the team is a chess move for the next season.
- Keep an eye on JJ: Her arc as a widow is going to define the emotional stakes of the upcoming episodes. A.J. Cook is doing some of her best work here.
- Don't hold your breath for Shemar Moore: While Derek Morgan is always a fan favorite, Moore is currently tied up with S.W.A.T. Exiles. A cameo is possible, but a full return isn't in the cards for now.
The cast Criminal Minds Evolution is smaller, but the performances are deeper. They’ve traded quantity for quality, giving us a version of the BAU that feels more human because it’s finally allowed to break.
To keep up with the latest shifts in the BAU, you'll want to track the official Paramount+ production updates, as filming for the next cycle is already stirring up rumors of more legacy returns.
