"Q&A" is the 15th episode of season 4, and the 83rd produced hour of Person of Interest. It originally aired on February 17, 2015.


Reese tries to protect a software programmer with a mysterious second life, but it’s unclear which side of her life the threat is coming from. Meanwhile, Claire, a young hacker who Finch tried to protect from Samaritan, reaches out to him for aid.

Origin of the Title

Q&A refers to Questions and Answers, and is often used to refer to questions asked by viewers or readers of a person or website that answers commonly asked questions. It is also known as a FAQ, or Frequently Asked Questions. The term applies to the questions being answered by Fetch and Retrieve's software, VAL. It can also refer to the question that Claire asked Greer about her risk of death.

Main Plot Points

The events in this episode are in Samaritan point of view.

  • Person of Interest: Anna Mueller, an employee at internet search company Fetch and Retrieve, who has a secret life. Former POI Claire Mahoney reappears, seeking Finch's help.
  • Reese moonlights as a security guard at the main office of Fetch and Retrieve, the internet search provider where the new number works.
