Well, it's not like it's all sunshine and roses in the zombie apocalypse. LOL
I thought it was a great episode......got the characters tired, hungry, dehydrated, and sick of being on the run.
The one scene I didn't get was the zombie attack on the barn. At one point they are all pressing against the doors, holding them shut from the zombies, and then the next, they're all asleep. Did the wind just blow the zombies away so they could sleep?
As for who the Aaron guy is.....spoilers below, highlight to read them.
In the comic series, Aaron is a 'recruiter' for the "Alexandria Safe Zone"......a town that was able to wall itself in and keep the whole area zombie free. In the comic he is gay and has a partner, so this would be the first out/gay character for the TV show.
