Prentiss has disappeared - without her badge and gun - as soon as her BAU colleagues piece together her connection to Doyle. They bring in an old friend, J.J., to use her role in the State Department to provide information on Prentiss' CIA past, and her connection to the international team that profiled Doyle and his role in IRA related terrorism. Some of what the team learn makes them understand Prentiss' behavior over the past month, but some of her past angers especially Morgan, who cannot reconcile what she did for her past job. As they learn more about Doyle, they realize that Prentiss, who they know has gone after him, is up against not only Doyle but his sizable army who will do anything to protect him. They also learn that of the profiling cell in which Prentiss previously worked, the only other surviving member is Clyde Easter, who they believe is the one who sold out the rest of the team to Doyle. As the BAU detain Easter, they have to see if he can or will divulge whatever information he has in time to save Prentiss.
