Camryn Manheim and Saul Rubinek Join 'Person of Interest'

TVLine

CBS' hit drama series Person of Interest is adding two familiar faces to the cast. TVLine reports that Emmy winner Camryn Manheim and Warehouse 13 alum Saul Rubinek will be appearing in upcoming episodes of the third season.

They are reportedly said to appear and will "anchor an emotional plot that will play out over multiple Season 3 episodes."

An emotional plot? Rumors that someone is getting killed off? Not necessarily related but...

I am so nervous.

Manheim will play Diane, a devoted wife whose husband, the brilliant Arthur (Rubinek), is slowly losing his mind. While the POI team risks putting her in danger, they must rely on Diane to break through to her husband in order to save both their lives.

The episodes are slated to air in early 2014.

A new episode of Person of Interest airs tonight. "Endgame" is rumored to kick off a high intensity arc that may leave fans shocked.
