All three are dealing with jobs that are less-than-ideal according to TV Guide on Tuesday. Finch is a professor, who has a "half-empty classroom and a department head breathing down his neck." Shaw is selling perfume at Bloomingdales. Reese is still "in the action" isn't feeling like he's living up to his potential.

"We couldn't resist the fun... of having these guys utilize a different skill in a fish-out-of-water circumstance," executive producer Greg Plageman told the website. "It's particularly fun with Reese and Shaw, throwing operatives into roles that they're accustomed to or particularly happy with."

The three are living under aliases to try and avoid the "roving eye" of the Samaritan. "Samaritan has a way of tapping operatives around the world in its own unique way," Plageman said. "Samaritan can see into people's personal lives and even detect personality disorders or certain individuals who can be coerced into doing things. We think Cara is a formidable opponent for our guys this year." The Cara he's referring to is recurring guest star Cara Buono who feature prominently this year on Person of Interest.

The drama Person of Interest returns this Tuesday at 10/9c on CBS.
