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.

"If you play by the right rules you will win. But I was wrong... I'm going to kill you..But I need to decide how far I'm willing to go."
1 June 2016 | by jeshu-42609See all my reviews

We have already seen the brilliance & class of Jonathan Nolan's writing, but this episode by is his masterpiece. The episode was tailored with such precision & it's sole purpose - make all the viewers enthralled by the action & emotional roller coasters in this episode. To all the #TeamMachine comrades who died valiantly for their beliefs in this episode... May you rest in peace. You will be missed and you will be avenged. Like Root said "They all made choices.. They all died for what they believed in... The machine is still watching over them..(They are) all simulations now." The most satisfying & scariest moment in this whole show "I'm going to kill you...but I need to decide how far I'm willing to go." Greer & Samaritan better start praying because Elias' prediction is about to come true.
