UPDATE. TVline is reporting that the fifth season just got truncated to 13 episodes which could mean that this might be the final season, although the shows creators have gone on record saying they never intended for season five to be the last, CBS might have other ideas. This is depressing news.
Person of Interest has been picked up for season five. Following an intense season four that saw many changes in the wake of Samaritan rising, season five continues that story of what the world looks like when a superintelligent AI is invisibly controlling all lives.
No word yet on Sarah Shahi reprising her role as Shaw.
