Criminal Minds: Evolution Season 4 has a lot of questions to address, but these 5 should be the top priority

As Criminal Minds: Evolution moves toward its fourth season, it finds itself in a unique narrative position. For the first time since the reboot began, the show has effectively cleared the board—Elias Voit is behind bars, the Sicarius Network has been taken down, and the BAU has (finally) caught its breath. But peace is a luxury that never lasts long in this universe, and if the past is any indication, the storm is already brewing.

Criminal Minds: Evolution Season 3’s finale didn’t just close a chapter; it almost looked like it was trying to close the whole book. It wrapped up long-running arcs, offered emotional closure, and yet, somehow left a subtle trail of breadcrumbs that hinted there’s plenty more story to tell. From psychological unravelings to shadowy unknowns, there’s no shortage of questions looming in the minds of viewers.

However, while there are many threads that could be picked up in Season 4, five burning questions stand out above the rest.

How the show chooses to address them may well determine whether the next chapter soars or stumbles.

1. What’s next for Elias Voit—rehabilitation, revenge, or retirement?

Voit may be shackled and en route to a maximum-security prison, but the season finale made one thing crystal clear: his story isn’t over. Despite his confessions and apparent remorse, Voit still fantasized about murder in the very last scene; proof that Sicarius isn’t dead, just dormant. Is he a broken man grasping at redemption? Or a predator waiting for a new opportunity?

What makes this more intriguing is that Voit is no longer a mystery to the BAU—he’s a known variable. If Criminal Minds: Evolution Season 4 brings him back (even briefly), the writers will need to carefully navigate whether he's a reformed anti-hero, a manipulative asset, or a ticking time bomb. One thing’s for sure: you don’t build a character this rich just to let him rot offscreen.

2. Will Tessa escape—or become the BAU’s new Hannibal Lecter?

Tessa Lebrun, a.k.a. The Disciple, is now in custody. But if there’s anything Criminal Minds has taught us, it’s that cages don’t always hold monsters. Tessa’s warped worldview, obsessive attachment to Voit, and calculated violence make her more than just another UnSub-of-the-week; she’s the perfect psychological wildcard for future storylines.

Could she stage a prison escape, sparking a deadly new arc? Or will she become an imprisoned consulting psychopath, offering her twisted insights on cases in exchange for something darker? Either way, keeping Tessa sidelined would be a missed opportunity. Her twisted bond with Voit and her unfiltered hatred for the BAU team make her a powder keg just waiting to go off.

3. Can Criminal Minds: Evolution replace Voit with a worthy new villain?

Let’s not sugarcoat it: Voit was a massive part of this series’ success. The Sicarius storyline threaded its way through three seasons, and Zach Gilford's performance added complexity to a role that could’ve easily been just another “killer with a gimmick.” With that chapter now seemingly closed, Season 4 faces its most critical challenge: finding a new villain who can fill that void.

The temptation will be to go bigger, badder, more theatrical. But the strength of Criminal Minds has always been in its psychological nuance. The next antagonist must feel personal. Someone who can infiltrate the team’s emotional core, much like Voit did with Ochoa—or, even more terrifyingly, with himself. The villain shouldn't just challenge the BAU’s intellect. They need to haunt their souls.

4. How will Voit’s confession shape the legal fallout?

Voit’s decision to confess without a deal changes the legal playing field entirely. It’s no longer about plea bargains or negotiations; it’s about consequences. But with a suspect like Voit, “justice” becomes a slippery concept. He confessed, yes—but does that mean he’s beyond saving, or is it a desperate act from a man afraid of himself?

This raises another dilemma: what happens if Voit becomes useful again? If another killer mimics his methods or threatens his family? Do the BAU cut him out for good, or find themselves reluctantly dragging him back into the light? His full confession may have been an ending, but it may also be the beginning of an uneasy, high-stakes alliance no one wants to make.

5. Is the BAU truly safe now?

With the Sicarius Network dismantled and its members exposed, the team should finally be able to exhale.

Wrong! Criminal Minds has never operated in a vacuum, and if history has shown us anything, it’s that evil doesn’t go extinct, it evolves. The vacuum left behind by Sicarius might even attract something worse.

The bigger concern? How much has the team changed in the process? JJ nearly shot Voit. Garcia cracked a code that exposed hundreds of killers. Rossi, once cynical and stoic, is now visibly shaken. And Tyler's official recruitment raises the question: who’s next to be pushed past their limit? The BAU may have survived Sicarius, but what if it broke them in ways they haven’t realized yet?

Final thoughts

Criminal Minds: Evolution Season 4 isn’t just a continuation—it’s a reset. The pieces are all on the board, but how they move next is anyone’s guess. With Voit behind bars, Tessa caged, and a world full of darkness still out there, the BAU may be out of the frying pan, but the fire is far from out.

If Season 4 wants to raise the stakes and keep the series fresh, it must grapple with the five questions above, and do so with the same nerve and nuance that made the last three seasons such a wild and twisted ride.
