Character mistake: Eli asks Rick, "Who was that guy I talked to? It was her father, wasn't it?" In the previous episode, Jack says, "I'm the last thing you will ever see if anything happens to my wife or my daughter." You'd think Eli would have registered what Jack said.
Character mistake: When Jack mentions the siege at Waco, he implies that the ATF's raid failed because an agent on-site screwed up. Their plan had actually been shot before the assault team even reached the compound; a reporter inadvertently compromised their advantage of surprise when he got lost and asked David Koresh's brother-in-law for directions, providing the Branch Davidians ample time to arm themselves in anticipation of self-defense.
