A suspicious looking man enters the post office and when Walter confronts him, the man is suddenly terrified, telling Walter he should be dead. The man attacks Walt with a box cutter and before slicing his own throat. Agatha attempts to stop the bleeding and tells Walter to take Robin home. Before succumbing to his injuries, the man tells Agatha to go to an institute. Agatha sees that, like Walter, the man is obsessed with the 23 enigma. Agatha finds the man's former work ID badge and visits the institute which is now fenced off and abandoned. There, she discovers a patient box labelled W. Sparrow but before she can look further a figure approaches her, giving her a fright.
