They were interrogating Commander Farrell on how he met Secretary David Brice who than berate him when the situation was "poorly handled" when it ended with Brice's mistress' death, Susan Atwell, and exposing Brice for her demise instead of seducing her to blackmail the Secretary of Defense. Even with the interrogators holding him a gunpoint and Schiller telling him that he's a Hero of the Soviet Union can't sway him, Schiller lets him leave the KGB, confident that he'll return and he has no where else to go.
As of 1991, of the KGB being dismantled, Schiller and his colleagues returned to America to monitor Farrell.
As of 2011, after Tom declared to cut ties with them and left, David confronted him about Tom sending the printout to Director Marshall which lead to him resigning, Schiller revealed himself to be Tom's handler before shooting him to death. After Brice's death being public, Schiller than murdered former senator Billy Duvall after overhearing his connections to the KGB. Schiller and his colleagues than found themselves being targeted by the Anti-Hunters.
Lt. Cmdr. Thomas "Tom" Farrell
