Finally got around to watching this. Zombie Merle was pretty sweet (from a looks perspective, not a story perspective). It was sad to see him go, I was holding out hope for some Mighty Ducks "Bash Brothers" episode or 10 in the future, but didn't think it would be long before Merle was gone. I agree with whoever said he couldn't go to Woodbury and wouldn't be accepted in the Prison group. The fact that they never really addressed or mentioned or did anything really (until this episode) to even attempt a reconciliation story line kind of sealed that fate as well.
I agree Glen is a goner. He went through a crazy time, manned up, became a tough guy kicking butt and taking names, showed leadership, realized his purpose in life and love...his story is done. What is left for him to do? He is no longer the errand boy or the weakling/shy guy - his love story is over, they aren't going to settle down and live happily ever after and they cant repeat Rick/Lori's story line with a stressed marriage/love story/baby/etc. Any other role he would assume in the group that he has matured into is already filled by Rick the leader, Daryl the killer, etc, etc. I will be surprised if he doesn't die in the finale and if he doesn't it means he will become a t-dawg character for a few episodes until he does die. Maggie still has story left...especially if Glenn does die, plus she is filling the non plot story role of the good looking woman there to kick butt and look sexy doing it.
I really like and agree with whoever posted the spoiler about Morgan and what will happen if he shows up. Didn't think of that and it makes sense (and would be a great way to handle that). Either his story is done or that happens I think.
