Multiple enemies converge on the POI team as they protect a dying man whose number has come up. They struggle to keep their enemies at bay but without Reese, who has left them and their mission behind following the tragic war with HR, being down one man could have catastrophic repercussions for the team.
- Aletheia (ἀλήθεια) is a Greek word meaning disclosure, lack of concealment or truth. It is associated with German philosopher Martin Heidegger's view of disclosure not as truth but as being open. As we see in the episode, the various characters have experiences which force them to be open, but not necessarily truthful, about events in the past and present.
- This two-episode arc makes several references to Finch's days at MIT with Claypool and Ingram. MIT is the Massachusetts Institute of Technology, one of the most select four-year colleges in the U.S. Best known for its curriculum in mathematics, science and technology, MIT emphasizes research and technology education, with a faculty including multiple Nobel Prize laureates. Although not part of the original ARPANET, it has a long history of research tied to the development of modern computer technology and defense. It also has a reputation, along with CalTech and Stanford University, for having a highly creative student body given to pranks and other high profile activities.
- Rudiger Smoot, a false identity that Finch created to open a bank account on a dare, refers to a common MIT student joke. Smoot refers to a non-standard unit of measure first used by undergraduate Oliver R. Smoot to measure the length of the Harvard Bridge as part of a fraternity initiation. MIT jokes involving measures in smoots (roughly 5' 7", Smoot's height) have become so well known that the ridges in the bridge are now one smoot apart, as opposed to the traditional 6'. Oliver Smoot went on to become chair of the American National Standards Institute (ANSI) and later President of the International Organization for Standardization (ISO), bodies charged with standardization of various units and measurements.
- The quote "The world breaks everyone and afterward many are strong in the broken places." is drawn from Ernest Hemingway's A Farewell to Arms, his romantic novel set amid the Italian Campaign during World War I. The novel was published in 1929, and is known for securing Hemingway's reputation as an American novelist.
- The beginning of this episode is on "Lethe". This is a continuation episode.
Bloopers and Continuity ErrorsEdit
- In the opening scenes, the video shot of Control exiting the elevator shows her with a yellow square when in fact she should have had a red square at that time.
- The license plate of the Acura Harold steals in the opening has the plate NSO-7946. This is almost certainly a digitally altered version of the plate NSQ-7947 seen on Hector Alvarez's Camaro in "Get Carter".
- Young Harold is seen hacking ARPANET with a homemade computer. This was previously referenced in "2πR".
- The date Young Harold hacks into ARPANET is October 27th, 1980. In real life, ARPANET experienced a 4 hour long outage on October 27th, 1980. Note: The outage was later shown to be caused by a hardware malfunction.
- The book young Harold gives to his father in the nursing home is "Eastern Birds" by Roger Tory Peterson.
- The Machine sends an actual message through Morse code. It can be decoded as "SORRY.(...) INCREASED PERSPIRATION. HEART RATE AND BREATHING ELEVATED. INDICATIVE OF FEAR.(...) 2 OCLOCK. 2007 ANTERIOR CRUCIATE LIGAMENT TORN. SURGICAL REPAIR PARTIAL SUCCESS. 2010 PHYSICAL THERAPY DISCONTINUED AGAINST DOCTORS ADVICE.(...) 8 OCLOCK." A fan-made clip of the Morse code scene with lowered frequency for those who could not hear it in the episode can be found here.
- The two "hard drives" shown in this episode are actually two 500 GB Linear Tape Open (LTO) cartridges, an industry standard for backup due to their high memory density and archivability.  These two LTO cartridges would most definitely be sufficient to contain the operating system for Samaritan.
- "The first one to talk gets to live." (Control, to Finch and Claypool)
- "We'll need some enhanced methods. Agent Hersh, do you have any ideas?" (Control)
- "Stealing a car. Almost dying. Reminds me of the old days at MIT, Harold." (Claypool)
- "The world spins on dreamers like you, Harold." (Finch's Father)
- "Harold doesn't need to chase. He's got a certain gravitational pull with the female population." (Claypool)
- "Seems everybody wants to lock me up." (Root, to Control)
- "It would be like giving a 5 year old keys to a jet: Irresponsible and stupid." (Root, on giving Control access to the Machine)
- "You should know better than to hit me. You're lucky to be alive." (Reese, to Fusco)
- "Claypool's been rocking footie pajamas for months." (Shaw, to Finch)
- "You think you're in charge. It's adorable just how wrong you are." (Root, to Control)
- "Nothing wrong with jail. Some of the best vacations I ever had were behind bars." (Reese)
- "I always said banks were meant to be robbed." (Shaw)
- "Well, I've got finesse coming out of my ass, Harold." (Shaw)
- "Civil liberties cannot be forged in blood." (Finch)
- "Violent revolt is an American value." (Collier)
- "There's a time for a hammer and a time for a scalpel. It's hammer time!" (Shaw)
- "I'm glad you built it Harold. Somebody would have built it eventually. For all our sakes, I'm glad it was you." (Claypool, to Harold, about the Machine)
- "Mr. Reese, I am inordinately happy to see you!" (Finch, at being rescued)
- "Lionel, your face looks good all covered up like that." (Shaw, to Lionel wearing mask)
- "All you need to do is give me your username and password. All of this could stop." (Control, to Root)
- "Thank you for your service. You have earned my highest esteem." (Greer, to the impostor Bank Manager)
- "My Samaritan. You are destined for great things." (Greer)
