Great episode. The walkers are just an episode or two away from overrunning the community, unless they somehow get them back on to the road, which it looks next week like it's going to be survival just getting back home. The wolves are crazy people man, I really expected Rick and the others to make it back to defend Alexandria. I never suspected it to be only Carol, Carl, Rosita and Aaron. Carol is bad, love her character evolution.
Morgan's character has to change, or he will be killed. I'd think we will get a backstory on him soon.
The other Alexandrians need Rick and company more than ever. Deanna decided to stay outside the walls and Spencer is nowhere near ready to fight. They had no idea what it was like on the other side of the walls. New characters were introduced and some never even had a line to speak. Great start to season 6, they just keep raising the bar.
Once it hits the fan the pacing of this episode was absolutely brilliant. The running battle within the walls of Alexandria was riveting. You really were rooting for the "Alexandrians" to beat off the Wolf's attack. Great direction and season 6 is off to a sizzling start!
