Great episode. Great season so far. I loved how they ran the timing. Not quite in line with the previous episode.
Enid: I think Enid is what we saw. A young girl that has learned that you have to do what it takes to survive. She must have seen a lot on the road before watching her parents get eaten. My guess is that they have run-ins with the Wolves or Terminus-type humans. They were part of a bigger group that got slaughtered and the family took on the motto of JSS. She always knew that the Alexandrians were too weak to survive and that the facility to was too big/spread out to defend. I did think there was a possibility she was a spy, but I can't imagine that's the case after the last episode, and she's certainly not a spy for the Wolves. The only way I can see that is if the Wolves have one of her parents or something (we didn't see them actually die). But prisoner/agreements doesn't seem like the way of the Wolves.
Wolves: I can't decide if the Wolves are feral humans or a cult. I guess it could be both. Humans are smart and social animals, so if they went feral they would still be smart and they'd band together. Like chimps, they'd attack other groups just for territorial reasons, and take their supplies. I thought the lack of guns was odd, but maybe they just feel the need for ammo/reloading is less effective than basic weapons. I'm sure we'll see more.
Morgan: His character bugs me. I feel that the show (and other shows) have done this character too many times. The guy that could kill an entire village attacking him... but chooses not to. It always backfires and then they regret they typically regret their morals. I'm sure we'll get a backstory on how he learned to fight and why he doesn't kill, but I'm not sure I care. I did think it was interesting, however, that Morgan still seems socially odd. Something is still up with him.
