In recapping this show every week, I often neglect to mention (except in passing) what is arguably the most important component of the Reese-Finch partnership: The Machine itself. We know more or less how it came to be (NSA-funded project headed by the presumed deceased Nathan Ingram) and how it's used by Finch to prevent crime in NYC.
But remember that The Machine is constantly being used by the government to scan for terrorists (and people pirating movies, probably). As efficiently as Ingram and Finch designed it and as streamlined as the NSA's protocols might be, an undertaking this massive is bound to draw attention.
And now it has.
