"Person of Interest" returned for its second season with the dynamic duo torn apart. Finch has been kidnapped by Root, who admits to being very impressed with his work in creating the machine. But what does she want it for? In a confrontation, he says he'll never help her gain control of it, but Root says that's not what she wants at all.
"I just want to set it free," she revealed.
Through flashbacks, viewers learned that the machine may be more sentient than it first appeared. Finch spent years interacting with it and training it as he would a child. And with Finch gone, the machine turned to Reese.
It was able to call him on a payphone and give him a coded message, using the Dewey Decimal System to present the social security numbers. But while Reese wanted the machine to help him find Finch, it simply gave him his next assignment.
Later, though, Reese risked the life of the guy whose number he was given to give the machine an ultimatum. He won't play by its rules anymore. He demanded it help him find Finch, because he simply isn't going to work without him. It appeared that he got through, as the machine called him with a new number.
Find out what it all means as "Person of Interest" continues on Thursdays at 9 p.m. ET on CBS.
