Complete story — includes the ending
Reese takes the case of Theresa Whitaker, who supposedly died alongside her family years prior. He discovers that the crime was in fact an assassination staged to look like a murder-suicide, and that there is still a price on Theresa's head. He tracks down the original hitman, who admits he let Theresa live out of a refusal to kill children. Finch locates Theresa, only to be cornered by another hitman; Reese intervenes in time to save them, leaving Theresa in Carter's care. Carter attempts to access Reese's police file via his fingerprints, only to find it redacted. In flashbacks to the early days of the Machine's development, Finch expresses concerns to his since-deceased business partner Nathan Ingram that the Machine would have to be shut down should the public ever learn of its existence.
