Remember the name we didn't recognize that popped up on the Machine's "danger" list on last week's Person of Interest? Well, we're about to find out about the mysterious "Maria Martinez" this week, and we've got a sneak peek clip for you.

Shaw and Fusco are outside the UN, surveilling Maria, their number of the week. This is when they realize that Maria is following a French diplomat named Rene Lapointe. Also, Fusco and Shaw actually make a great comedy duo.

Finch and Reese must delve into the murky waters of international politics when they are given the number of a former government contractor who is stalking a UN diplomat. Also, an enemy attempts to gain an upper hand on Root.
