So, an interesting episode with a few different twists. A few observations:
Darryl's Very Bad Trip
Darryl was pretty bad beaten up this episode and came precariously close to dying a few times. The people he met up with were from what sounds to be a sort of failed Woodbury. Just when you think Darryl will get them to come back with him, they betray him, take his bike and his crossbow. Darryl gets a cool truck instead (conveniently hidden in the same way he hid his bike), but I think this brings up a larger concern. Usually when we see people make the sort of mistakes Darryl did, they aren't long for the world in the Walking Dead, could this be a sign that Darryl is next on the chopping block?
Sasha and Abraham Try to Psychoanalyze Each Other
Sasha and Abraham are probably the two most psychologically unbalanced people on the show, so having them try to help each other work through their psychoses is a bit of a bizarre choice. Nonetheless, while they wait around for Darryl they discuss their issues and somehow actually help each other out a bit, albeit not before Abraham loses his damn mind trying to get an RPG. Abraham gets lucky, and seems to have a new outlook on life, stealing a marine's dress blues to wear around just before Darryl rolls up with his cool truck.
Peace of Mind Shattered
At the end of the episode, our off track apocalypse adventurers call home, and receive a single word message back from someone (it sounded like Rick to me...but I could be wrong), the voice said "Help". Certainly, that call for help sounds ominous given the state we left Alexandria in, and next episode certainly looks like Rick and company are about to have issues with the walkers. Note: If you happened to think it may have been Glenn, unfortunately you're wrong, Norman Reedus already said it isn't him.
Still No Glenn
Like I said, I'm pretty sure Glenn...whatever form he's going to be in, won't be back until the mid-season finale, two more episodes left.
