chunk: Bourne arrives at a hospital at 415 East 71st Street, having figured out Landy's coded message. Outside, Bourne meets Landy and gives her the Blackbriar files before going inside. Vosen also figures out Landy's code and warns Dr. Albert Hirsch (Albert Finney), who ran Treadstone's behavior modification program, that Bourne is coming. He follows Landy inside the building but is too late to stop her from faxing the Blackbriar documents out. Meanwhile, Bourne confronts Hirsch on an upper floor and remembers that he volunteered for Treadstone. As Bourne flees to the roof, he is confronted by Paz, who asks, "Why didn't you take the shot?" Bourne repeats the dying words of The Professor in The Bourne Identity: "Look at us. Look at what they make you give." Paz lowers his gun, but Vosen appears and shoots at Bourne as he jumps into the East River.
