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

As season 4 continues to bring in the action on CBS, Team Machine on Person of Interest have to face an enemy from the past in all-new exciting episode. With an upcoming election in danger, will Jim Caviezel (Reese) and Michael Emerson (Finch) will become 'Prophets' to save political candidate?

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 in the season premiere, the Samaritan hired an assassin to find and kill them.

According to TV Guide, "Prophets" centers on a talented political pollster (guest-starring Jason Ritter) as his number comes up for Team Machine. When his normally accurate predictions start going wrong, the pollster begins to suspect the election has been rigged. Someone is forcing their political candidate to win, no matter what.

Check out a sneak preview here:

If you have seen the previous episode, Wingman, then you know Root (Amy Acker) has a stash full of heavy artillery to be used against Samaritan. Now we get to see Root in an impressive action sequence, which involves her two guns and the blonde-haired assassin. As if they never run out of bullets, Root is upstairs, shooting downwards, while the assassin downstairs is shooting upwards.

If you have seen Brotherhood, not only does Team Machine have to deal with Samaritan, they also have to deal with a tough, smart, and cunning gangster named Dominic. Shaw didn't know she had the criminal in her hands, even while she was torturing him.

Person of Interest continues Tuesdays, on CBS at 10pm. Readers, are you excited to see Jason Ritter, son of the late John Ritter, on the show?
