The two of them find out with help from Morland that the bomber is connected to an Iranian diplomat in the organization, Hashemi, who is bent on deposing Vikner as leader. They meet with her only to realize the enormity of the organization and to learn the reason why Morland was targeted by Vikner. Some in the organization, like Hashemi, wanted Morland as the new leader until Vikner played his hand. Sherlock, Joan, and Morland work together to frame Vikner for a federal crime, only to find out that he was tipped off by a contact inside the FBI and is in the wind. Morland, in an attempt to protect his son, then contacts Vikner, who thinks he's going to be able to kill off Morland. Morland, however, has allied with Hashemi, so Vikner is killed instead by her men. Morland meets Sherlock on the brownstone's rooftop, telling him that he has taken over leadership of the organization with the aim of dismantling the network from within and explaining to him that it was the only way to guarantee he would not lose his son. He also promises that the group won't have a presence in New York and prepares to return to London. | |||||
