The next episode of "Criminal Minds" season 12, "The Anti-Terrorism Squad," will see the team deal with one of the harshest and most brutal fallout of bullying.

Led by Prentiss (Paget Brewster), the Behavioral Analysis Unit (BAU) investigates the murder of two families where a teenager from each family managed to survive.

The "Criminal Minds" season 2 episode 5 preview shows Garcia (Kirsten Vangsness) doing some research on the Facebook profiles of the victims.

Garcia discovers that not all of their fellow students were sympathetic about the tragedy. Mixed in the flood of heartfelt condolences sent to them by their classmates on Facebook are messages that state they deserved what happened.

This leads to a realization that the students left unhurt in the murder were bullies. It turns out they had a record in school about harassing fellow students. This could be the key to solving the case in the upcoming episode.

This definitely sheds light on the warning left on the promo for the episode, which stated: "Every clue is a deception and every victim is not who you think they are."

As Garcia did some research, she felt a bit old after she finds herself being annoyed by the number of selfies some young people share in social media.

Before she gives Prentiss and the others the important information she finds, Garcia first complains, "How many pictures of yourself do you really need and basically making the same expression?"

She stops herself when she realizes that she has become "officially not young," although Rossi (Joe Mantegna) had a better word to use, which is "timeless."

"Criminal Minds" season 12, episode 5, "The Anti-Terrorism Squad" was supposed to air last week, but due to the World Series, it was moved to Wednesday, Nov. 9, at 9 p.m. ET on CBS.
