Main Plot Points
- Root's identity is revealed
- Alicia Corwin kidnaps Finch but is murdered by Root
- Root stages an assassination in order to kidnap Finch
- Carter and Fusco learn about one another's relationship with Reese
- Simmons sees Fusco with Carter and Reese
- A firewall is a piece of hardware or software that controls what data can move into or out of a computer system. It is designed to provide protection to a network or single computer against data from sources that cannot be trusted, notably the internet. It is these firewalls that hackers must get around to enter complex systems. The name derives from construction firewalls designed to keep fires out of buildings, and has become a metaphor for the mechanisms we use to protect ourselves from others.
- The box around Caroline Turing is yellow, indicating her awareness of the existence of the Machine.
- To celebrate Person of Interest airing on Netflix starting September 1, 2015, IGN.com asked Jonathan Nolan and Greg Plageman to pick a few of their favorite episodes. Nolan picked "Firewall" because it was one of the greatest experiences he ever had working on anything, especially since Root is one of his favorite characters to write for.
- The episode began on May 17, 2012 and just after Donnelly escorted Carter into the NYPD Real Time Crime Center which had Reese and Root on a large monitor showing footage that occurred two hours before, then flashes back to two days earlier, where the action begins.
- There are certain similarities between this episode and “Pilot”:
- Both episodes start with a flashback and end with Reese looking into a security camera. Moreover, the camera used by Reese to contact The Machine in this episode is the same location as that used at the end of “Pilot”.
- The person of interest in both episodes is female and thought to be the victim. As it turned out, both women were actually the perpetrator.
- Also, both episodes involved the POI hiring HR, except they were hired anonymously in this case, and Turing put the hit on herself while Diane Hansen ordered the deaths of other victims.
- After an earlier episode that featured a faceless and nameless Root, they were excited to bring the character back, and even gave her an engaging musical cue for her. Before writing the episode, they knew they wanted to include HR and also decided to add someone who would learn about the machine, but with malicious intent. Two weeks before they were to begin shooting the episode, they decided to rewrite it to include Root.
Bloopers and Continuity Errors
- The date on Reese's phone shows May 17 although following to the overall timeline in the episode, the hotel escape happens on May 18.
- Zoe's clothes change color: at 5:30AM, when she calls Reese to tell him that she was going back to Turing's office, she's wearing a black dress and a white coat. A few minutes later, when she checks Turing's laptop and finds out that she's truly Root, she's wearing a red dress and a black coat.
- Finch is stated to have rigged the cell towers so that only his cell phone would work. However, Reese, Fusco and Carter are shown to have working cell phones as well.
- This is currently the only season finale episode to feature a full-length title sequence.
- Fusco and Carter learn that they are working for the same person, Mr. Finch and are able to work together to help Reese.
- Reese's phone number is (917) 285-7362. Notably, this is the same number Finch later gives to Sameen Shaw in Relevance. Calling this number leads to Harold Wren's voice mail.
- This NYPD Officer has a "CIB" collar pin. CIB stands for Combat Infantry Badge and is issued by any branch of United States Armed Services. NYPD are allowed to wear military ribbons and CIB on their uniforms
- With Reese in the backseat Carter and Fusco drive by a huge billboard for the movie "Think Like A Man" which had Taraji P. Henson in a starring role.
- "Just because you're paranoid doesn't mean they're not trying to kill you." (Reese)
- "Define wrong person." (Finch)
- "It's an article of faith for me that all criminals, however clever, eventually slip up." (Donnelly)
- "Let's go make a mess." (Simmons)

- "He's in danger now. Because he was working for you. So you're going to help me get him back." (Reese)
- "Trust is complicated Lionel. For example: I'm sitting in a police car with one cop who tried to murder me and another who spent six months trying to lock me up. So you'll forgive me if I take things one step at a time." (Reese)
- "Well, we should all grab a drink together sometime." (Reese to Carter and Fusco)
- "So nice to finally meet you, Harold. You can call me Root." (Root)
- Zoe Morgan: She put the hit on herself. She was trying to lure you out into the open.
