— Mark Snow
Origin of the Title
- Number crunch refers to the process of doing large calculations. In addition, crunch is a colloquialism for trying to manage a big task, often under pressure and with very little time. In this context, the title refers to the larger than usual number of persons of interest the Machine has sent the team, and the challenge that comes from trying to protect all four at once before while finding the threat. There may also be an element of the physical impact of the car crash which sets events in motion.
Main Plot Points
- Persons of Interest: Claire Ryan, Matt Duggan, Wendy McNally, and Paula Vasquez, a group of strangers who witness the car accident of a Congressman's son and steal a bag of money from the car.
- Carter's shooting (“Get Carter”) is investigated
- Womack, Tyrell Evans and Mark Snow are introduced
- Carter helps Reese for the first time
- The quote "The pen is mightier than the sword" is printed on the pen that Finch, posing as blogger Thomas Paine, gives to Jim Hallen. The phrase was coined by British playwright Edward Bulwer-Lytton in the mid-1800s. It captures an often-expressed belief about the power of words versus the power of violence, espoused by Euripedes, Shakespeare, Thomas Jefferson and Napoleon Bonaparte, among others, in their writings.
- Reese finds a picture of the young Finch and the young Nathan in the apropos book "The Ghost in the Machine."
Bloopers and Continuity Errors
- While reviewing the crash footage, Carter identifies Matt Duggan's car as a Ford Escort when in fact he was driving a Honda Accord.
- When Things Explode by Unkle - End of episode.

The opening shot, where a car crash takes place is not Roosevelt Drive. First,a point of fact about the New York City street grid; There is a Franklin Delano Roosevelt Drive (or FDR Drive for short), which is a major artery which hugs the periphery at the eastern edge of and originates very near the tip of Manhattan (one of Five Boroughs which compose New York City),& there is a Roosevelt Avenue which spans out across eastern Queens (another Borough) but no Roosevelt Drive within the Five Boroughs.
That being said, the actual roadway is Joralemon Street (the Borough of Brooklyn). More specifically the part of the roadway which bends to run alongside the water's edge of New York Harbor. Furthermore, it is bounded by Atlantic Avenue to the South and Furman Street (with the Brooklyn-Queens Expressway, or BQE for short, very nearby) to the East.
After Detective Carter determines that Detective Foster does not exist, she is trailed by two CIA Field Officers, Snow and Evans, as she is walking along Flatbush Avenue from Fulton Street to Livingston Street in Brooklyn.
- According to the Machine's archival footage, the final scenes of the episode occurred on December 15, 2011, the same date as the episode's original airing. (“Super”)
- This is also the first episode where we see multiple 'numbers'.
- Starting with this episode, all the main characters have met each other in person, discounting the pilot episode.
- In real life, the Ducati store and the hair salon are at the same address.
- The assault rifle John uses outside the girls' house is a Coharie Arms CA-415 modified with a 10" barrel, polymer magazine and Leupold CQ/T scope. This weapon, made in the USA, is a popular clone of the H&K 416.
- The Space-time continuum is a concept of Einstein's General Relativity. To breach it, you need to disconnect time from a location in space i.e. time-jump or time travel.
- "I've breached the space-time continuum.... Not really." (Finch)
- "I'm sorry but I'm not letting you back on the street looking like this." (Wendy, to Reese)
- "Careful what you look for Mr. Reese or you might find it" (Finch)
- "Allegedly... I like that" (Carter)
- "My vest got shot. It can take some time off" (Carter)
- "Yes, and I'm hearing rather too much of your lower intestine. Could you move your phone from your belt to your jacket pocket? " (Finch, to Fucso)
- "Detective Fiasco?" (Aide)
- "Thank you for saving my life." (Carter)
- "Hello John. I'm surprised you wound up in New York City. I thought you'd get yourself a cabin in the woods. Montana, maybe... It's time to come home John. The slate's been wiped clean." (Agent Snow)
