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.

Don't know what to say!!
1 June 2016 | by voldoreSee all my reviews

Some say its good some say its best.... But you don't have to be a die hard fan of the series to understand, marvel and appreciate the level of creativity and twist for this particular episode. I never thought I will miss these characters after I close my monitor off. But I am missing these characters... even though there are still three more episodes to go.For the series' fans this was a treat (and a little sour too).

Thank you for making this series and characters in such a way you almost start living with them. I do feel sorry for few characters who are not going to see the final battle. But still a masterpiece of an episode from a masterpiece series.
