When Cyrus Vanch is released from prison, he attempts to reclaim his position as the leader of the underworld. His first goal is to take down his biggest enemy, Arrow. Meanwhile, Ollie shows Moira "the List", and questions her about names on it. Thea becomes miserable when she begins her CNRI internship; Detective Lance makes a horrible mistake, putting Laurel in the sights of Cyrus Vanch.
So is the only Betrayal going to be Oliver feeling betrayed by his mother. Will Moira find out that Oliver is Arrow? In one of the later episodes it says that she is going to be making a move against Merlyn. Could this be the beginning of a joint attack on Tempest and/or the List by Oliver and Moira? What do you think?
