Fear the Walking Dead season 8 has brought back multiple characters who were thought to be dead, which is making the show seem unrealistic. The latest episode, "Iron Tiger," reveals that both Troy and Charlie miraculously survived their presumed deaths. This isn't the first time the show has backtracked on character deaths, with examples like Madison and Daniel. The return of Charlie, who was on the brink of death from radiation poisoning, seemed unlikely but was explained by her treatment with PADRE. However, her return is short-lived as she sacrifices herself in the same episode.
