He objects to Reddington's plans for a takeover of the Port of Tankulu in Indonesia while Milos Kirchoff is active. He later tries to convince Laskin and Russo, two of Red's other operatives, that Red is acting recklessly and needs to be stopped. He tells Vargas that he will side with Milos Kirchoff. However, the price is that Red is assassinated within the day and that he wishes to witness the killing. Later, Demakis, aided by Vargas and the others, corners Reddington and admits to defecting to Kirchoff's syndicate.
