Criminal Minds: Evolution Season 4 Episode 9: The BAU’s Biggest Trap Yet Is About To Spring

The Fan has finally been unmasked. But knowing who he is might be the easy part — episode 9 is about to prove that staying one step ahead of him is another story entirely.

When Does Criminal Minds: Evolution Episode 9 Drop?

Criminal Minds, now in its fourth Evolution season on Paramount+, releases episode 9, titled “Badder Blood,” on July 16, 2026. New episodes have streamed weekly on Thursdays at 3 a.m. ET since the two-episode season premiere back on May 28.

What Happens In “Badder Blood”?

The BAU finally identifies the true identity of the Fan, the season’s central antagonist — but staying ahead of him proves difficult. That advantage reportedly draws the team into a trap tied directly to David Rossi’s past, raising the personal stakes for one of the franchise’s longest-running storylines. It’s a signature move for the Paramount+ era of the show, which has leaned into serialized, season-long arcs rather than the case-of-the-week format from its CBS run.

Where Things Stand With Elias Voit

This season has built much of its tension around Elias Voit, played by Zach Gilford, who has reportedly been plotting from behind bars. “Badder Blood” appears to be the moment that long game starts costing the team, setting up the season finale, “Special Agent Garrido,” which promises a final showdown between the BAU, the Fan, and Voit.
