Patrick Forbes
A sex offender suspected of abducting Dustin Powers. He was a suspect when he was about to be sold in an online auction, but was written off as he, according to Agent Katie Cole, wasn't smart enough to pull that off.
Kevin Rose
A 14-year-old boy who ran an adult chat room, showing himself to his audience. He had received pictures of Dustin Powers from Hayden Rawlings, who was operating under the screen name Mehtevas. He eventually agreed to meet up with Rawlings in order to help the BAU arrest him.
Kevin Rose's Father
The father of Kevin Rose was said to have been physically abusive by Jason Gideon. This is evidenced by bruises that are visible across Kevin's body.
Other pedophiles
Several other pedophiles appear in the episode, mostly only as IM names on computer screens. One of them can be heard during Kevin Rose's live performance, giving him instructions.
The Perfect Storm
Amber Canardo's father and brother
The father and brother of Amber Canardo, both of whom would physically and sexually abuse her in the woods during her youth. When there was an opportunity for authorities to formally investigate the abuse, Amber's mother protected her husband and son by saying Amber lied. The two presumably continued their abuse afterwards. It is unknown what happened to them during the events of the episode.
Amber Canardo's boyfriend
A man who was dating Amber Canardo before she met her husband Tony. The boyfriend assisted Amber in her initial string of killings before somehow dying, presumably by Amber's hand. His body was then kept by Amber in a cabin they used for the murders.
Psychodrama
Karen Sheppard
The mother of bank robber-turned-spree killer Caleb Sheppard, Karen was addicted to painkillers. Her husband died at some point, which presumably worsened her addiction (it's unknown if she became addicted before or afterwards). She also abused her son and daughter, causing the latter to commit suicide and the former to act out and be in-and-out of prison. Her status afterwards is unknown. The abuse she delivered was a driving force in Caleb's later crimes, even once projecting her on one of his victims.
The Last Word
The I-80 Killer
A serial killer targeting co-eds along Interstate 80 in Indiana. According to Prentiss's profile, he is an organized white male in his early thirties who is quite the charmer, able to smooth talk educated women who know there's a predator out there into his car. Eight of his eleven victims were reported missing on Friday mornings and were theorized by Prentiss to have been picked up at the Ranch House, a well-known nightclub in Gary that has a popular ladies' night on Thursday. Coincidentally, Interstate 80 was also the same route prolific serial killer Frank Breitkopf took while looking for his victims all across the country.

Fear and Loathing
The White Stallions
A white supremacy movement in a New York suburb. Inspired by a series of murders of African-American girls disguised as hate crimes, they assaulted an African-American teenager.
Jones
Sarah Danlin's rapists
A group of men who raped future serial killer Sarah Danlin on February 19, 1998, during Mardi Gras. The only one identified by name is Ronnie Tibideaux. Due to a disagreement between the two detectives investigating the case, Sarah was eventually persuaded by one of the detectives, J.R. Smith (who knew Tibideaux), into dropping the charges against the men. This would later lead to Sarah committing her murders. Interestingly, a flashback of the rape showed two suspects, although a police report indicated three offenders.
Honor Among Thieves
Fyodor
The partner of rogue Russian mobster Lyov Lysowsky, whom he assisted in a series of "mutilation kidnappings" of Russian immigrants. He was later stabbed and killed by Lyov to remove loose ends.
