Ive watched POI since the beginning but last night confused the crap out of me. Too much going on. I still havent figured Finch out, if he has a bad side. And are the other 2 guys that showed up where the machine was missing, government workers? Of course the one guy shot his boss after talking on the phone. But who are they? Also, who is the old guy from the episode last week where John didnt kill him. He was telling John about Finch and the laptop. Ive seen him on other episodes but really dont know who he is. TIA And yes, shaw is good looking. But root is also.
To me, it felt like it wrapped up alot of that, but here goes:
Finch, knowing the Government was not exactly trustworthy (via what happened to Nathan), he set out to find a way to have a virus he created (with hidden codes to unlock The Machine), be used by someone who wanted access to the Machine (Whether it was the government or an outside party like Decima, it didn't matter). He hoped to teach the Machine another way to protect itself, and hoped it would do so. Which it did, when it facilitated having itself moved to some unknown location. Also, even in God Mode, it wouldn't release specific information of where it was located, which I think was also something Finch put in the Virus.
Finch wasn't bad, per se, but he realized his actions could cause others to be hurt.
He must have came across Reese's info, and his connection to that Laptop (Virus), and wanted to help him out of of guilt of hurting him (Reese going after the laptop meant he wasn't there to save Jessica)
The 2 guys entering at the end (well 3, counting random guard), are government workers. Hersch is a CIA/government Assassin, and the other guy is one of the managers of the Program (in Season 1, I think he's listed as "Special Counsel" in the federal government, so like a Lawyer/Attorney General?). He's in charge of the Government's "Relevant List" actions, and Hersch was his right hand man. But obviously, there's someone higher, who had enough of the Special Counsel guy.
The old guy, Greer, is a manager in the Decima Organization, who also has a boss we haven't seen. This is an organization that believed the virus bit they recovered from that Laptop, could create a situation to take control over an immensely powerful machine, but failed due to the actions of Finch, Root, Reese and Shaw. Greer is play by Chris and Jonah Nolan's Uncle, John Nolan. He played a Wayne Boardmember in Batman Begins and The Dark Knight Rises ("The Apple has fallen very far from the tree, Mr. Wayne")
Shaw is a very nice looking woman. So nice looking, I keep seeing tons of woman watchers who can't stand her, for some "unknown" reason. ;)
