To me it just looked like the guy grabbed Dog and threw him, which caused Daryl to yell. I thought Dog was dead, until he showed up later. I thought it was dumb that it took Dog forever to start attacking the guy, and then once he did, Daryl just sat on his ass and watched, instead of getting up and killing the guy. I also don't know why the Reapers are following Pope. Sure, they bonded in Afghanistan, but you'd think by now, after seeing his level of crazy, they would have chosen a new leader. Also, they have yet to explain whey they just go around sneaking up on people and killing them.
