Note:
I will have one for Season 5 when/if season 4 is official. I have my mind set up about that, I am thinking there will be more characters to introduce in S5, Neegan, Morales and family, etc. and that it will slow down from the pace of S3 and S4, but only because they are on the road and won't have an entire town coming at them, like Woodbury.
