War is coming on Tuesday's Person of Interest.On the midseason finale, the Machine used Root (Amy Acker) as an avatar to have a one-on-one chat with fellow artificial super intelligence Samaritan. When those talks devolved, Samaritan decided to show the Machine just how quickly it could create global chaos by setting its sights on the U.S. stock exchange.In the exclusive sneak peek below, Root maps out for Finch (Michael Emerson) just how serious this threat is — the collapse of the financial system could create revolts, starvation... and war. "Our cold war just turned hot," Root says.Fortunately, the Machine has created a fail-safe for Samaritan's attacks. Unfortunately, it has to be deployed on-site at the stock exchange and Team Machine is down a person with Shaw (Sarah Shahi) in the wind.
