Of the seven identities hidden and protected from Samaritan - Finch, Reese, Shaw, Root, and Root's hacker team, each with a dedicated rack-mount server for the task - Detective Lionel Fusco was not one.

Control cites the 6th Amendment to the U.S. Constitution to move the "trial" along. The sixth amendment sets out the rights of the accused in a criminal trial. They include the right to be informed of the charges against them as well as the right to a speedy trial, the right to an impartial jury of one's peers, the right to counsel, and the right to confront one's accuser.
Collier responds to Control that he, "knows the Bill of Rights." The Bill of Rights is the first ten amendments to the U.S. Constitution, which guarantee a number of personal freedoms, limit government and establish states' rights. In the scene in the storage container, the Bill of Rights appears on the back wall, written in ink visible only in black light.
At the end of the episode, Root's voice-over references Pandora's Box. The Greek myth of Pandora's Box tells the tale of an unopened box (sometimes a jar) that contains all the miseries of the world. It remains closed until the curious Pandora, the first woman on earth, opens it, releasing its contents. She quickly closes the box, leaving one small being, hope, behind. Pandora's box has become a metaphor for actions that have significant, negative and unexpected consequences, or which will cause nothing but trouble.
