Tyrese is cool. I hope he and his wife become part of the main group. I loved the scene where he was practicing shooting at the walkers.
Has it been established that is is wife or his sister?
Regarding episode - I liked it as well. I think the point of this episode was to reaffirm the fact that the Governor has completely lost it.
Also IMO to setup where Milton is going to die because he's betrayed the Governor.
