For six months, Rossi has been on a one person crusade to catch Everett Lynch, ever since Lynch almost killed him. Many of Rossi's actions have been behind Prentiss' back, and as such she feels they need to have a "talk". Things take a turn when a murder occurs that Rossi believes is Lynch's doing comes under the purview of the entire team as their next case. The team as a whole, including Prentiss who is still leading things, believes Rossi needs to broaden his view to look at the evidence objectively and not try to fit the evidence to Lynch. This latest victim is discovered in Baltimore County, and not the American south where Lynch has exclusively worked. The victim is a twenty-something male, and not a forty-something female that fits Lynch's victimology. While the latest victim did have the skin off of his torso removed post-mortem - unlike the faces of Lynch's female victims - the bodies were not burned like Lynch's previous victims. Another common factor is the fact the victim probably met the unsub on the same dating website that Lynch used to lure his female victims. Eventually, more male victims emerge fitting the same victimology and M.O. Although Rossi had interviewed Grace Lynch, who is behind bars for the crimes she committed with her father, over the course of his one person crusade, Prentiss wants him to focus on the Lynch angle by not only reinterviewing Grace, but also interviewing Everett's mother, Roberta Lynch, both who Prentiss is having transferred to DC for questioning. The rest of the team will continue on with the investigation as per normal course. It is a casual comment that Reid makes to Rossi that may be the turning point on discovering whether the unsub is Lynch or someone else.
