Another home run of an episode as Peter fights back and hits the Observers where it hurts most by disabling their Wormhole for transportation. Oh so they thought. In a desperate move on Peter's part, he comes up with the idea of jacking the tech out of a captured Observer and implanting it in his own neck to level the playing field so to speak. Now, I do think this was a cool idea and probably the only way the Resistance could conceivably overthrow the Observer Regime. But I've always wanted them to be able to do so with their own human spirit and ingenuity instead of having to rely on technology that wasn't their own.

I loved the scene of Olivia coming to terms with Etta's passing while watching an old home video of a young Etta at her Birthday Party and calling Peter, begging him to come home because she loves him. The way the episode ends is pretty riveting to say the least.
