* In "MIA", Mrs. Thompson's pacemaker was implanted by [[spoiler:Samaritan]]. Even if she makes it out [[spoiler:after Reese leaves her]] at the end, it's pretty obvious what's going to happen to her once [[spoiler:Samaritan's]] feeds get back online.

* In "Booked Solid", Hersh notes in his conversation with the Special Counsel that it took him longer than he thought to escape prison. Given that his original goal going in was to kill the four men in suits (Reese and the three mercenaries), the delay might have been him killing off the other two mercenaries. It might have just been to cover loose ends (if they tried to retaliate over Hersh killing one of the trio in "Prisoner's Dilemma"), or in case Reese was a separate threat coincidentally caught with the "man in the suit".

* In Season 4, Shaw has started to take the role of MissionControl more often. Normally you would think a BadAss ProfesionalKiller would be totally unsuitable for such technical work until you remember [[spoiler: Shaw was an operator for the ISA, an organisation which specializes in communications and surveillance.]] While she would never be able to hack [[spoiler: like Finch and Root do, she would have sufficient experience at coordinating the other members of Team Machine from a desk and other basic technical work]].

* John Reese was likely the first number from the Irrelevant list that Finch was able to save. (His number came up prior to the events in New Rochelle, and then he was contemplating suicide when we meet him in the Pilot episode 7 months later.)
** Disproven as of 'RAM'

* Extremely subtle but Finch becomes panicked when someone he cares about like a POI or John is around a bomb. Later in "God Mode", we discover why [[spoiler: Harold's OnlyFriend Nathan Ingham was killed by a bomb while Finch had his back ruined in the blast. After this trauma, when someone he cares about is around one, Harold immediately drops everything and if possible is willing to die trying to save them from getting blown up like in the case of John during "Dead Reckoning"]]

* In "Panopticon," the [=PoI=] is Ali, an Egyptian immigrant who owns an electronics shop, and is being forced to build a private wireless network for a drug gang. The network he builds is similar to improvised wireless networks constructed by the demonstrators in the "Arab Spring" protests in Egypt and Tunisia. Explains why they would be going to him for one.

* For a terrorist group, Vigilance seemed to be particularly well armed and funded compared to most with their members using top of the line European firearms such as Heckler and Koch MP5 submachineguns and having a computer virus capable of knocking out New York's power grid for an extended amount of time. [[spoiler: But when John Greer reveals that the Decima Technologies corporation, which specializes in developing such viruses and could easily afford to provide the group with high quality firearms has been the entity behind Vigilance, it makes a whole lot more sense on how they were able to acquire such equipment.]]

* During "A House Divided", why does Reese eventually agree to the seating arrangement during the car trip with [[spoiler: Hersh]]? Because as they don't trust each other, sitting [[spoiler: directly behind Hersh puts Reese in a prime position to empty his SIG-Sauer into the man's back in the event of a premature betrayal as they go to rescue their bosses.]]

* Fusco knows "a place in D.C. that charges by the hour." He's divorced, which suggests that while he might legitimately be bunking in somewhere cheap, it also suggests one possible way his marital infidelities, if any, occurred.

* "[[Recap/PersonOfInterestS03E17 /]]": Why does Decima need a superfast 89 [=GHz=] helium-cooled processor to run Samaritan, while The Machine can run on more conventional (albeit very good) hardware? Arthur had [[[[Recap/PersonOfInterestS03E12 just gotten the Samaritan software to work when the government shut the project down]]--because The Machine had gone operational. The Machine was at a later stage of development, and its code had been [[http://en.wikipedia.org/wiki/Program_optimization optimized]]. If Arthur had been given the time to finish developing Samaritan, he would have been able to refine Samaritan's code so that it didn't consume so much processor power.

* RealLife example. Jim Caveizel, Reese's actor has many friends amongst the Navy SEAL veteran community. Reese's WeaponOfChoice, the SIG-Sauer P-226R which also happens to be the sidearm of the SEALS could be a subtle nod to them.

** Fun fact; there's strong evidence that a lot of abuse (up to half of straight relationship abuse, depending on the source) is F>M, and lesbians, depending on which stats you use, have the highest likelihood of all. ''So how many more numbers is Harold missing''?

* Why is Arthur able to remember Finch and all the shenanigans they got up to in college so easily when he has trouble remembering anything else in "Lethe" and "Aleitha"? Think back on the school song they sang together in "Lethe": The last three words as ''always remember MIT''.

** From "4C" as well. Reese is going to Istanbul. Why? Because Julian Sands in "Critical" mentioned they'd crossed paths at the market there, and Reese wants to follow up on that.
