The whole turnstile thing seemed really dumb to me, I mean it was a good scene but how do Noah and Glen not know that dude was going to do that? He had just left his friend to die and heard the dying guy say they had left the others to die last time too.
Also, are walkers really that strong to where they could pull Noah towards them with Glen pulling the other way? They can barely walk and are decaying.
Also, they took him back. After Glen knocks him out he tells Eugene to tie him up. Then in the van, Eugene is pointing a gun at him as he reads the line from Noah's journal (can't see the dude, but who else would he be pointing a gun at?)
And of course another black man dies.
