Wow. Epic.
Best episode in two seasons. Takeaways:
Glenn is becoming Rick: take charge, do the right thing, badass survivorman.
Morgan has a reckoning coming now that Carol's on his ass, and I imagine he finds a way to integrate his eastern philosophy with his need to survive.
The Alexandrians continue to prove to be fuckups. Spencer, you gigantic douchebag.
Sam is going to play some role in stopping the Wolves. Creepy little Children of the Corn motherfucker.
The slow buildup to the tower falling into the fence was pretty great. Missing the big picture (the sawing of the tower supports) for the details (the blood flowing through the bullet hole) was kind of ham-handed, but effective. I wonder if we see Elvis the psuedo-scientist play some role in defeating the Wolves since he seemed focused on the sound of the sawing in the tower.
Glen and Enid are going to encounter the Wolves (with whom I assume Enid is familiar, if not a member). I think they'll play it as Enid holding Glenn hostage until they can break away from the marauders.
