Milton Bobbit

A series of seemingly unconnected murder-suicides are attributed by Red to a life insurance claims adjuster named Milton Bobbit (Damian Young), who is able to convince terminally ill people to carry out the acts in exchange for financial rewards for their surviving family members. The targets of the murders are ultimately discovered to all be part of a clinical drug trial for type 2 diabetes that caused people to die, and Bobbit himself is found to be terminal. Elizabeth, Ressler and the team must catch up with Bobbit before he himself takes out the next victim: the doctor who headed up the trial. They manage to arrest the doctor and let Bobbit commit suicide. In Cooper's office, Red has a look at Bobbit's client list which seems to matter much to him.

After Red gets some DNA results on Tom, he determines that Craig (real name "Christopher") is not Tom's brother. Elizabeth traps Chris in his hotel room and tries to get answers. Tom calls Chris while Elizabeth, Red and Dembe are in the room, and mentions "Berlin". Red demands to know what's in Berlin, but a frightened-looking Chris says he cannot say anything. After Red threatens that he'll find a way to make him talk, Chris hurls himself through the hotel room's window, falling to his death, after which Tom attempts to convince Liz that Craig had to fly home.
