Spoiler alert for anyone who hasn't yet watched Criminal Minds' wild season finale.
In Season 12, Criminal Minds has taken its story to places formerly untouched by its procedural narratives, giving Reid his own complication-filled serialized arc that other characters entered and exited while dealing with the perma-presence of big bad Mr. Scratch. And while the show has used a crossover or two in the past, audiences have never seen anything like the giant vehicular catastrophe that happened at the end of "Red Light," which put the majority of the main characters in dire straits. If you were as shocked as we were, here's showrunner Erica Messer's reasoning behind the finale's ending.
In terms of bucking predictions and subverting expectations, Erica Messer and her creative team knocked this one out of the park. Criminal Minds is a show about violent and dangerous people, but it's very rare for one of the leads to run into this kind of potentially fatal situation, and this was far more than just one of the leads. We might have even expected a more minor version of this cliffhanger to play out once the team actually reached Mr. Scratch's location, but before we could even consider what would happen, all hell broke loose. (More on everyone's fates here.)
The team was traveling in two SUVs which were taken down by a strip of spikes that popped off the ground, and that "accident" would have been bad enough, but then an 18-wheeler entered the picture and slammed into everyone. From the looks of things, Alvez, JJ and Walker were the ones most likely to live another unsub-stopping day. But things looked way more worse for the wear when it came to the vehicle that Rossi, Lewis and Prentiss were traveling in. Considering Paget Brewster and Aisha Tyler both became regulars in Season 12 -- in part because of the firing of Thomas Gibson -- it's unlikely they'll be going anywhere. But now that Erica Messer is embracing plot variations like this, no one is safe.
Below, Messer told TV Guide a bit more behind the general decision process to bring the cliffhanger into the episode.
In the meantime, Criminal Minds: Beyond Borders' two-part season finale will air on Wednesday, May 17, at 9:00 p.m. Head to our summer TV schedule to see when all the other returning and premiering shows will pop up in the coming months.
