This was a great episode. We finally find out the origins of Michael The Observer Child (he's a genetic anomoly from the future who was scheduled to be terminated but disappeared into the past, Donald's identity is September and Nina sacrificed herself so The Observers wouldn't read her.
The pace of the episode was nearly perfect and was full of action and plot reveals to boost us into full speed for the 3 Part Series Finale (that airs over two weeks)
I can't wait to finally find out the full plan and how the red rocks, the beacons, the thought unifier, and Michael all fit into the plan to defeat the Observers and probably reset the Timeline. If they do do a fresh reset in the Finale, I hope whoever survives retains the memories of this timeline, because I dont want the "what was the point of it all feel to the show after it ends.
Loved this episode though. I really want that Etta Resist Poster!
