Meanwhile, Reese and Shaw are on the hunt for a pair of brothers, Gabriel and Erik, who are harbingers of doom for the entire city.

Things take a turn for the worse when Reese and Shaw realize that Gabriel and Erik are not working alone. They are backed by a powerful organization that provides them with a seemingly endless supply of money and resources. As the duo investigates deeper, they come across evidence that suggests that the Machine's predecessors were heavily involved in the Brotherhood's operations.

Finch, who is still working to bring the Machine back up, makes a startling discovery.
