Root is back and undercover in a new Zap2it-exclusive clip from “Person of Interest.” In the above video, Root confronts Fusco and warns him to watch himself. He does what any normal person would do in response: He leaves.

The synopsis for “Person of Interest” Season 3, episode 19 “Most Likely To …” reads: “Reese and Shaw pose as alumni at a high school reunion in order to keep eyes on the latest POI. Meanwhile, Finch and Fusco travel to Washington, D.C., to investigate the motivations behind Vigilance’s latest attack.”

“Person of Interest” airs Tuesdays on CBS at 10 p.m. ET/PT.
