Storyline

The first act following the Machine and Samaritan's cold war summit, which ended in a standoff, is that Samaritan starts to take the market down by crashing the New York Stock Exchange. Samaritan's plan entails a few small rebounds to prevent the fail-safe system from kicking in. Reese, Finch, Root and Fusco know that the best way to combat this take down is not to deal with anything on the market floor, where the minority of trades are actually made, but to deal with the server in the Exchange's basement, the server which processes the vast majority of trades. Shaw is not with them as she still needs to hide from Samaritan's cameras. As such, Shaw has her own task off site. Both the foursome and Shaw's tasks end up not being as straightforward as they would have liked, each placed in a precariously life threatening situation. Root has to wait for the Machine to evaluate all the possible options for success before moving. The question becomes if there is not one option which has a ... Written by Huggo

Goofs

While Harold is teaching the machine chess and is talking about the history of the queen and its use as a sacrifice, he forces the machine's queen into a position where he can take it with his rook, but then when the camera enters slow motion when he makes his move, it shows him taking the machine's king instead, despite none of his pieces having been in a position to do so. Furthermore, the king is never actually taken in chess, because if it's in a position where it could be taken (check) then the player is required to remove it from danger, either by moving it or by blocking the piece threatening it. If it's impossible to get the king to safety, then the game is over without the king ever actually being taken (checkmate). See more »

Quotes

Harold Finch: On chess. "It's a useful mental exercise. Through the years, many thinkers have been fascinated by it. But I don't enjoy playing... Because it was a game that was born during a brutal age when life counted for little. Everyone believed that some people were worth more than others. Kings. Pawns. I don't think that anyone is worth more than anyone else... Chess is just a game. Real people are not pieces. You can't assign more value to some of them and not others. Not to me. Not to anyone.

One of Many Breathtaking Episodes and Probably Best So Far
12 January 2015 | by djmsek-211-591256See all my reviews

Huge fan since episode 1. Can't really add to what's already been said by others, it's my favorite series. This episode was movie theater quality - they should consider doing 2 hour shows as great as they have been. Every single episode I have watched of this show was top-notch, and the population at large that watches this show gets quite the "big brother" education along the way, not something that many action genres can lay claim to. The second you set foot outside your door in London, a camera + facial recognition software identifies you within seconds, to assume that situation doesn't exist here in America is foolhardy at best. This series may very well be the most prophetic of all in years to come. Acting is ridiculously top-notch - even from "bear" that great Belgian Malinois. It's the most solid 10 out of 10 in all of television right now, and should be defined as "required viewing."
