While CBS has renewed Person of Interest for another season, it was given a reduced order – not the full 22 episodes that has been customary. And when CBS announced their fall schedule today, Person of Interest was not on it, revealing it will be held for midseason, all of which is making many wonder if this means the series is going into its final season. At CBS' Upfront press event this morning, I asked CBS president Nina Tassler what she could say about whether Season 5 will be the end for the show.
