Finch goes on a mission to destroy Samaritan by unleashing the most dangerous computer virus known on it. In the process, Finch and the Machine continue to discuss in balance if she has done more good or bad. She provides him with simulations of what would have happened to several different people if she had never existed. Finch will also learn if the Machine has truly learned that self-preservation is the top priority. He too will find how much collateral damage he is willing to exact in the process. Meanwhile, Reese and Shaw receive the next number from the Machine, that belonging to an alias for Greer. What they believe his number means is that the showdowns between he and Finch and thus between Samaritan and the Machine are imminent. But most importantly, they know in following the leads to Greer, they will also find Finch.

Did You Know?


The simulations the Machine shows to Finch are reminiscent of It's a Wonderful Life (1946). In the film, the main character is convinced he world would be a better place had he not been born. An angel shows him what the world would have been, helping him to realize his life did make a difference in the lives of others. See more »


The virus ICE-9 has a file name extension of 'exe' which is a Windows OS only executable extension. When Finch breaks in to NSA data-center to upload the virus, it says on screen that he is uploading ICE-9.exe to all NSA servers. It is however, next to impossible in a data-center that all servers run on Windows OS. Servers running on Unix OS are definitely present. So the ICE-9.exe virus would have no effect on servers running on Unix OS and thus Samaritan would not be affected completely by this virus. See more »

Can't stop the inevitable!!! whether you like it or not
14 June 2016 | by voldoreSee all my reviews

Yes, this episode was one of the greatest episode from the series. But it was heartbreaking to see the desperate choices made by Finch and specially THE MACHINE. It's the choices which makes us what we really are, and if the Machine makes these choices (better than people like Greer and team Samaritan) one can only ask who is more human.

The decision Harold would come up with in this episode was clearly the only option left to him but the Machine's acceptance and its omniscience was something only a human companion could show. Again a masterpiece and thought provoking episode from one of the greatest series I have came to know so far!
