The Person of Interest world has changed.
So states a mystery woman portrayed by Cara Buono in the first sneak preview for Season 4 of the CBS drama, as revealed this weekend at Comic-Con.
The former Mad Men actress and Fred Weller both make their first appearances in the following video, which also takes fans back through Person of Interest Season 3.
In new footage, we see Sam and Root lying low in a chic department store, along with Elias looking displeased to see Reese again and Root warning Harold that a war is at hand, “so pick a side.”
