New Promo Trailer For Person Of Interest’s “2 Pi R”

Did you ever have one of those dreams where you’re back in high school? Well Finch’s dream comes true when he finds himself masquerading as a substitute teacher in Person of Interest’s next episode ‘2 Pi R.’

With Reese (Jim Caviezel) in custody, Finch (Michael Emerson) returns to high school to investigate a genius teenage hacker who apparently needs protection … from himself. Meanwhile, Carter (Taraji P. Henson) undertakes a dangerous mission for the FBI. While we’re not exactly sure what Carter’s up to, we definitely approve of her sexy new undercover look.
