At this point, even if the showrunners made a dramatic change and decided to turn Andrea into the character she is in the book, I would probably still want her dead on the show. She is just terrible. Every time she takes a half step forward, she runs a marathon backwards. In the context of the Walking Dead universe, Andrea knows that if a person is bitten then they die and come back as a zombie. So here is a guy who has been bitten, laying at her feet. He is suffering, dying, and pleading for somebody to help him. What does she do? Asks somebody else to do it for her and then gets upset when somebody actually steps up and does it! Listen, I am all for being civil in an uncivilized world and I actually agreed with Dale a lot of the time...but what did she expect someone else to do? Magically cure the man who had been bitten multiple times? Bandage him up and he'll be fine? All she wanted was for somebody else to shoot him so that she didn't have to.
Aside from that, this episode was really very bland. I really wasn't a fan of Rick's last minute freak out in front of Tyreese and his group. These are characters who should already be on the show to begin with so to see them struggle so hard to become part of the group is a little frustrating to watch. I understand the group's reluctance to allow strangers into their new home, especially with all the things they have been through but eventually they need to trust somebody.
I am also curious why nobody seemed to think of the idea of blindfolding Merle, taking him back to the prison, locking him up, and interrogating him since, you know, they live in a prison and all. If the group is so concerned about the Governor and Woodbury, wouldn't it make sense to attempt to gain some valuable information from a person who lived there and was a big part of their security force? I'm sure that Merle wouldn't have had much of a problem with giving up information and it would have kept Daryl around long enough for everyone to have cooled down and figured out a plan.
