Do we really need spoilers, now that the episode is done? To me, that calls back to Rick& Herschel & Glenn, when he shot those guys in the store. It was VERY vague to me, and I could see Carl's view.
While Andrea seems to have been "stupid" for her loyalty to Woodbury, Tyrese & his sister seem to have come to their conclusion in a timely, logical manner. I really hope for next season that they show some flashbacks, that explain his character & Walker experiences...i.e. how he was able to stay relatively grounded through all this.
I think this was a good finale...not quite like last year, but some good resolutions.
