I too thought it looked like the hitch hiker was killed by a car or something other than a zombie, looked like he had been smeeeeeaaaarrreeeddd down the road, but whatever. Nothing came of it so I guess it doesn't matter.
So any predictions on what role Morgan will play in the rest of the season, if anything? Did they take all of the weapons? It looked like they took a duffel bag, meanwhile the place was stocked better than the NRA museum. Maybe they come back and get more stuff, but it didn't seem like Morgan supported Rick's plan.
