It was a very dark and twisted episode when compared to the previous episodes. You felt that darkness right from the beginning. The writers have shown that you can tell the intensity of the story (without me getting into spoilers) in a very unique way. Says a lot about the quality of Person Of Interest. I was wondering that this season was rushed because it was the last and got half the usual count from CBS, but the writing has been just the right speed and manages to tell a story at the same time develop more shades to its characters. Thank you Jonathan Nolan and J. J. Abrams, this work of fiction will be an inspiration for many story tellers!
