If it isn't clear before this episode, it's definitely clear now. Rick is, no question, one of the best/realistic characters in the show in terms of both the character writing and the acting. I don't know how many times he get praised but Andrew Lincoln is doing a great job in his role and Rick was easily the most intriguing figure in this episode. As for others, like Carl and Enid, I found their interaction to be cute, but plain. Sasha, the COD player goes off into the forest and attempts to tier up, but of course was saved by Michonne. Overall, a good episode with slow pacing but a really good ending, with Glenn and Rick carrying this episode.
