The problem is they need to add in something else for those ADD watchers. This is a Zombie Diaries episode.The issue is the pacing of the show.
These characters have been around for like 2 or 3 seasons and the writers are just now developing them. It's just odd pacing in general. I thought the episode was decent, but I really think that we should have seen a lot more of these kind of episodes earlier on in the series
