'Person Of Interest' Season 4 Spoilers: Will Jim Caviezel, Michael Emerson Join "Brotherhood?" [WATCH]

As season 4 continues to bring in the action on CBS, Team Machine on Person of Interest gets ready to receive more numbers with the all-new exciting episode. With the lives of two innocent kids in danger, will Jim Caviezel (Reese) and Michael Emerson (Finch) join the 'Brotherhood' to save them?

As we previously mentioned, The Machine was beaten by a much more powerful Artificial Intelligence, known as The Samaritan. To stay far away from Samaritan's radar, Finch (Emerson) and his group assumed normal lives to prevent themselves from getting caught. But how long can they remain undetected, when there's cameras on the streets and everyone has a cellphone, feed Samaritan's intel?

In an interview with Entertainment Weekly, executive producer Greg Plageman reveals the stakes have just gotten higher, "While the Machine has been forced underground to a degree, the power of Samaritan is that it can recruit operatives all over the globe. It becomes a more powerful, almost omniscient enemy to our guys."

Check out a sneak preview here:

According to CBS Express, in the latest episode, entitled Brotherhood, Reese's cover job as a detective at the NYPD all of a sudden becomes complicated. From what we can tell in the video, Reese needs Finch's help when two young siblings become targets of a gang investigation. Because the brother and sister duo have the stolen money, gang members will do anything to get it back?
