Finch realizes that an incredibly skilled hacker is responsible for the entire thing. He tries to manipulate his way into the hacker's network but ends up putting himself in a trap. Finch and Reese have to destroy their phones and hang out in hotels and the library for the time being. Realizing they're a tad screwed, Finch enlists the help of Zoe. Zoe manages to figure out that the congressman's business partner more than likely wanted him dead. She lends her skills, which apparently in this episode are nothing more than a conversation, and manages to get the proof they need. While all of this is happening, Reese is off kicking ass in a subway bathroom while wearing a hoody. I approve.
Finch gets a call from the creepy hacker and for one wild moment I thought he was in cahoots with her. But then when the hacker contacts him again, she calls herself Root and considers Finch an opponent. Who is she? Does she think what they're doing is a game or a competition?
