15. Q&A

Reese and Finch work to save the life of Anna Mueller, a software programmer at Fetch and Retrieve. She is being targeted because she expressed concern over the results VAL, a mobile app designed to aid users, is giving to people with depression that has resulted in suicides. Finch discovers a nautilus during the investigation and is contacted by Claire Mahoney (from " Nautilus ") who tells him that she had recovered some source code from Samaritan and wants him to use it on his laptop, but he's suspicious. Later, Claire reveals herself to be a Samaritan agent and leads Finch at gunpoint to a school run by Samaritan to convince him to join, but he refuses.

Root rescues him from the agents and shoots Claire, who escapes and hands Finch's laptop to Greer. Back at Fetch and Retrieve, Calvin Mazer, the CTO, holds Fusco and the CEO Lauren Buchanan at gunpoint and reveals that he altered VAL's source code to target people with depression, gambling problems and debt, for the sake of the advertisers. Reese rescues them, and Calvin is arrested. The next day, Greer attends a board meeting at Fetch and Retrieve.
