4. The Arrival

Complete story — includes the ending

A mysterious cylinder emerges from beneath the Earth in New York City, so Broyles enlists the trio of Olivia, Dr. Bishop and Peter to investigate it. However, others also seek it, including the Observer ( Michael Cerveris ), a man who only watches events as they unfold, and another willing to kill to retrieve the cylinder. Dr. Bishop hides the cylinder against the wishes of the rest of the team, owing a debt to the Observer for saving his life and that of his son years earlier. An unknown man abducts and tortures Peter for information regarding the cylinder's location, and learns its placement through the ideas Peter has absorbed from his father through osmosis. The man takes him to a cemetery housing a tombstone bearing the name of Robert Bishop and finds the cylinder. Olivia shows up after learning the location from Walter and kills the man. The object burrows back underground before either side can discover its purpose. Peter encounters the Observer, who demonstrates telepathic abilities before shooting Peter with a yet unknown weapon. Standing in the kitchen, Olivia later sees John Scott in the entrance.
