The season finale of Criminal Minds ended on a humdinger of a cliffhanger when not one, but TWO SVUs carrying several BAU team members got caught in a deadly trap involving an 18-wheeler smashing into the cars before the episode cut to black, leaving the fate of several characters in limbo.
The season closer ended with Reid figuring out who the mole inside the FBI from a serial killer cult was and holding her at gun point. Unfortunately, he couldn’t take her out because at the last second she revealed that the group had Garcia (Kirsten Vangsness) held hostage. She offered Reid an ultimatum to come with her and join the cult, or Garcia would be next on their victim list. It seems that Kirsten could hold out and not return for the following season.
