Damn, for a moment there you thought Carl was going to get killed or something... but looking back to it, they wouldn't have done that because then Rick would go emo again and that would go against his transformation in this episode. That scene of him biting the guy's throat was pretty incredible... and now we know that human teeth is strong enough to bite flesh, lol (at least in that alternate universe).
By the way, I'm always amused by the random walking encounters. Like that glasses dude that was surrounded by walkers. How in the world did you manage to get surrounded by walkers? Also, I don't get how people can never seem to outrun walkers because the walkers are actually rather slow. Also random occurrences of walkers appearing at such inconvenient moments.
Ugh, still no idea where Beth is, and it looks like Tyreese + Carol + Judith aren't at Terminus yet. At least most of them are reunited <3
