Spoiler: showAlso, regarding the hitchhiker, I really didn't like the fact that he had no weapon or anything yet he's somehow survived more than a year. Obviously there are circumstances that he could be without a weapon but even if I were run out of a camp or whatever, I'd still find a stick or rock or something to carry around with me.
That and it would have been an interesting twist if we somehow discovered after the fact that he was actually a guy that escaped from Woodbury and he could have given them insider knowledge (like Tyrese for the Governor).Spoiler: show
To be fair he could have a gun or knife on him that we did not see, as he was only seen from a distance. He probably had something (small weapon/ammo/food) in his backpack, hence Michonne driving back to get it. You tend not to carry around unnecessary extra weight when zombies are after you. I would add that any character that has been alive that long would be smart enough not to YELL for long periods of time, no matter how badly you wanted that ride.
It was nice to see Michonne break out of her shell this episode, Rick letting her drive was a nice touch at the end.
