Instead of the usual one, the machine spews out four numbers of seemingly unrelated people: NYU lecturer Claire Ryan, waiter Matt Duggan, hairstylist Wendy McNally and unemployed Paula Vasquez. A grouping of numbers like this generally means to Finch that they are however somehow connected. In tracking the first name on the list, Reese is too late as that person is found dead. As such, Reese believes the best thing to do is for each of himself, Finch and Fusco to follow one of the remaining three apiece to ensure they all stay alive. Some of the three prove to be more elusive than their respective tracker anticipated. In further searching, Reese notices that two have increased their spending of late. And Finch learns that all four were at the scene of a fatal car crash two days earlier. From those two discoveries, Finch and Reese are able to figure out why the four are targeted, but they have to find out who is behind the killings, which seems to have a connection to a congressman and...

Did You Know?


The book Reese leafs through at Finch's place is 'The Ghost in the Machine' by Arthur Koestler. 'Ghost in the Machine' is a phrase coined by the Oxford philosopher Gilbert Ryle to describe René Descartes' mind-body dualism relationship. In the case of Person of Interest's arc plot, Koestler's book subtly hints that The Machine may be developing a soul, or already has. The soul is famously called 'Ghost in the Shell' in the Japanese manga and anime classic by Shirow Masamune. See more »


When Carter is walking down the street talking to Fusco on her cell, there is a lady in a black leather coat standing at the top of the subway stairs who notices the crew. She pauses at the top of the steps, smiles and watches the camera as it follows Carter down the street. See more »


Detective Lionel Fusco: What did you tell 'em about the CI?
Detective Joss Carter: The truth. He was taken out by an unknown shooter.
Detective Lionel Fusco: The guy, you got a good look at him this time, didn't you?
Detective Joss Carter: No. Not his face.
Detective Lionel Fusco: Well, maybe that's a good thing. 'Cause you know, it would be hard. You don't know whether to thank the guy or arrest him.
Detective Joss Carter: No, that'd be easy. I'd arrest him.

An episode to keep you wanting more...!
2 January 2012 | by whatt12See all my reviews

POI just gets better and better...or maybe because I prefer character development over strictly procedural stories. This episode in particular had a lot of main character interactions.

The stand-alone story was as interesting as always, but the over-arching plot line is reeling me in! So little is known about the background of the main players, in particular Reese and Finch; the writers are wisely doling out their information very slowly.

In this episode we learn just a bit more about Reese, but only enough to wonder where the story line will go from here. Can't wait to see how the ending to this episode gets resolved!
