Person Of Interest “2 π R” Images

We’re not sure what the formula for calculating the circumference of a circle has to do with Person of Interest’s next episode. We can however tell you that “2πR” will see Finch (Michael Emerson) going undercover as a high school teacher substitute teacher (he’s probably not going to need to stay up all night planning a clever disguise with this one) to protect a teen genius who reminds him of his own adolescence as a child prodigy.

Meanwhile, Carter (Taraji P. Henson) takes on a dangerous (read dangerously glamorous!) mission for the FBI.

Check out these images from the episode below, and catch “2πR” Thursday January 3rd on CBS.
