The following are spoilers for Criminal Minds: Evolution.
In the first episode of Criminal Minds: Evolution, BAU boss David Rossi’s (Joe Mantegna) wife, Krystall (Gail O’Grady), is killed. Sadness and anger begin to consume Rossi. The seasoned profiler goes down a dark path when Agent Prentiss (Paget Brewster) tries to talk him out of it.
Prentiss speaks to Gideon and says to Rossi, “A long time ago, Gideon told me to be careful not to keep quiet. Because it means I don’t trust my team anymore.” For Gideon, the grim nature of the job required profilers to work “between silence and anger”. Talking also means that you are not alone with your problems.
Ironically, that turned out to be the case rossi was the one who gave Gideon this advice many years ago. But he cherishes this reminder to communicate and share what he’s going through with the other people in his life. Prentiss also tacitly reminds Rossi of Gideon’s ultimate fate: he didn’t talk about his doubts or pain, and it finally left him alone.
