Person of Interest fans, we've got a treat for you. Or should we say treats?

The CBS hit returns Tuesday, March 18 with an all-new episode, titled "/." So what does "/" mean, you ask? Well, a forward-slash is code for "root path" in the programming world, which means we'll be seeing the return of Root (Amy Acker) in the episode. Can we get a huzzah?!

To celebrate the show's return, as well as Root's reappearance, we're exclusively sharing the opening six minutes of the episode with you. In the episode, Root and Finch (Michael Emerson) clash when they are both assigned the same person by The Machine.

Oh, and Arrow fans will be happy to see a familiar face in our exclusive sneak peek...
