Criminal Minds: Evolution ended its 17th season with the BAU partying while elsewhere one of its main characters was in a life-or-death situation, but his fate isn't all that uncertain. We're left with questions about what led to that end for Voit (Zach Gilford) and what it means for the future.

And thanks to TV Insider's interview with showrunner Erica Messer, we also have some teasers for what to expect in Season 18, including which agents will be at the center of the trauma (after Joe Mantegna's Rossi and Paget Brewster's Prentiss were in 16 and 17), which only leaves us with more questions. And what about the sibling of that agent who was mentioned in the finale?

Below, we discuss these and other pressing questions for Season 18.
