John discovers that Lucinda’s numbers are dates, death tolls, and geographical coordinates of major disasters over the past 50 years, including the Oklahoma City bombing, September 11 attacks, and Hurricane Katrina, as well as three more yet to happen. He visits Miss Taylor who, despite showing signs of Alzheimer’s, tells him of the scratching on the door left by Lucinda. The next day, John leaves to pick up his son where he witnesses a plane crash that takes 81 lives and realizes that it was the first future event on the list. John becomes convinced that his family has a significant role in these incidents: his wife died in an earlier event, while Caleb received Lucinda’s message.
