Feeling like his time is near, Finch hopes to get some answers directly from the Machine before he locks her down, while in the process not wanting his friends to die on his behalf. Finch continues to have philosophical differences with Root about giving the Machine the tools to defend herself, those which were not the rules he wanted when he created her. Finch may have subconsciously predetermined his fate when the next number provided by the Machine is his, meaning that his cover as college professor has been blown. Regardless of Finch's feelings on the matter, his friends intend to protect him to their own deaths if that's what it takes, as in Reese's words Finch is just the next in the latest of numbers he was hired to save.

The best episode of Person Of Interest so Far
6 June 2016 | by mvqaSee all my reviews

"Can you hear me?"

While I am really mad that they cancelled this show, I am really glad they are ending it with a bang.

This is the best episode I've seen in a very long time on any show. It's full of action, excitement and emotion, a lot of emotion. From the very first second the pace is really fast and you are completely entertained. And what can I say about the end? The last minutes were really emotional and at the same time exciting. You know you are watching a great show when you don't want it to end.

I can't wait to see the final 3 episodes.

This is the right way to make an episode #100.
