The group is united, another point I've been satisfied with throughout Season 6 so far. All of the promotional material pointed towards the same story all over again, one involving Rick's leadership decisions being questioned by everyone else, despite being suitably correct for a brutal situation. Carter provided some early opposition, but he quickly came around to Rick's approach, and died soon after. A mercy-killing...by Rick. Alexandria is no longer just a pit for festering feuds and civil war, it's a united camp fighting against the enemy. That theme should (and MUST) continue into the second half of the season and beyond.
