All kinds of awesome, the slow melodic lead up to Welcome to the Machine was incredible. I missed that was the indestrucable case, good catch.
One thing i missed, when did the night-vision goggles come into play? I didn't see them being used.
My guess for next season, and there BETTER be a next season, rebuild the Machine in a way that can beat Samaritan. Finch is a better programer than Arthur was.
