It's been ten days since the machine has provided a number, which means Carter has had ten days of dead bodies piling up. Finch discovers that a company called Decima is responsible for the virus which is causing these problems of inconsistency. The machine finally does dispense a number, it belonging to Ernest Thornhill, whose business of late has been buying up pay phone companies. As Finch and Reese track Thornhill, who they have yet actually to see, they find out some important information about him and exactly why the machine dispensed his number. But also aware of that fact is Root, who, using her own brand of persuasion, convinces Finch that they need to work together to battle Decima and the virus. Reese becomes aware that Root is back in the picture, he who gets some help from an old acquaintance in tracking Finch and Root. Their competing goals will all come to a head at midnight Eastern time, when the virus is scheduled to do its job. Meanwhile, Carter, in conjunction with ... Written by Huggo

Did You Know?


When Root meets Finch at the park, the machine tracks them. Usually, people are tracked with a white box; admins (John and Finch) are tracked with yellow boxes. In this scene, however, both Root and Finch are tracked with yellow boxes. See more »


Harold Finch: You try to harm her in any way...
Root: I don't want to hurt Grace. I'm not a sociopath, Harold. Believe me, sometimes I wish I was. The things I've had to do would've been so much easier. I don't like taking lives. But I will. Because I believe in something more important. I believe in your machine.

"I am not a sociopath, Harold" (dialog)...
27 November 2014 | by (North America) – See all my reviews

"... Believe me, sometimes I wish I was ... the things I have to do would have been so much easier" (dialog)

This review is really about Amy Acker, and in my opinion this series is ALREADY so good that any episode with Acker puts it over the top.

If I am not being clear, that is a GOOD thing.

I understand that Acker had a career in daytime TV before Angel but, as any fan will tell you, it was her work on Angel as a returning Goddess (you had to be there) that really became the breakout.

And this is the odd part. She is not really a full spectrum actress. Meryl Streep does not spend sleepless nights worrying about Acker.

I have watched Amy on countless "Lifetime" specials and she is pretty one-note.

So I have developed a theory.

She can play normal and she can play full-on loony, and that is her range. Pick one.

But when you think about it, that is still a pretty impressive range.

And in this episode especially, she is more fun than a barrel of hammers.
