Person of Interest executive producers Jonathan Nolan and Greg Plageman have revealed new information about what's to come for season 3.

With Sarah Shahi's promotion to a series regular, there will be new dynamics explored for her character, Samantha Shaw.

"We think the fun of her character is that she has a complementary set of skills that we're going to start to explore," Plageman told BuddyTV. Nolan said that they would be exploring the similarities between Samantha and Reese (Jim Caviezel) in the upcoming season.

The duo also confirmed that Amy Acker would be back for season 3. Her character Root was last seen in the season 2 finale in an insane asylum getting a phone call from The Machine. Enstars previously reported that Acker had expressed interest in wanting to return to the show for season 3 but said that the producers had not yet talked to her about returning.

They said that one of the central themes they would be tackling this season is the idea of an entity getting angry at the lack of privacy in the nation, mirroring people's current outrage about government wire-tapping.

With production beginning on the third season of Person of Interest, even more details are leaking out from other sources. SpoilerTV reported Wednesday that episode 2 of the new season would be called Nothing to Hide. The episode will include the introduction of Det. "Joss" Carter's (Taraji P. Henson) new rookie partner, Avery, who has some secrets.

The show is moving to the 10 p.m. Tuesday timeslot for the first time, after airing on Thursdays at 9 p.m. for its first two seasons.

The third season will premiere on Tuesday, Sept. 24 at 10 p.m. Watch the final minutes of the season 2 finale here:
