We finally got a look at the other side of the Machine (it's actual purpose - counter-terrorism), and it was interesting. It looks like it operates exactly the same way - gives you a number, nothing more. I did like how operatives on the counter-terrorism side have blue squares, as opposed to the yellow squares John and Finch have (but apparently not Fusco, Carter, or Leon).
Talking about yellow squares, Finch is amassing himself quite a team! He and John do the work, Fusco and Carter provide backup, and Leon looks to be the odd-job guy. In addition, Zoe pops up every now and then to lend John a hand, and it looks like Shaw may very well become a recurring character who can operate exactly like John (it will be interesting to see, if she does return, if she's used as the leader of a second team, allowing Finch to tackle two numbers at a time).
In terms of the "bad guys", it's not as black and white as it may have appeared at the start of the second series, but nor is everything scattered:
* Stanton and Snow are gone for good, so we don't need to worry about them. But do we need to worry about the guy who gave Stanton Finch's name?
* Elias has only been seen a couple of times, and appears to be an ally when it suits him. He may be controlling things in the city still, but he is not posing an explicit threat.
* 'Pennsylvania Two' (a name that comes from the press release for the series one episode No Good Deed) describes himself as "as close to control as you'll get", and seems to be in charge of the operatives who act on the numbers the Machine deems relevant and dangerous. I think he's also one of the original eight people who know about the Machine, and he acts to keep it secret. I don't think he's "bad", he just doesn't know that Finch is still involved with the Machine.
* Hersh. The fixer for Penn. Two who was sent after Alicia Corwin and John. Seems like a bad egg, but one that is only following orders.
* Root. Clever girl, infiltrating the organisation that protects the Machine! I'm not sure about others, but at the end of in last weeks episode I was wondering if she was playing Root on orders... until Penn. Two mentioned she'd only been there a couple of months. She's obviously there to get information on how to find the Machine.
I'm worried about the Machine, as it's started to glitch. Nothing major yet (apart from the anomaly detected in the opening credits), but CCTV footage isn't as smooth as it usually is, and there's the odd flash to a blue screen covered in binary. Is this going to get worse until the day the payload from Stanton's malware is activated?
