Fear the Walking Dead season 8 has brought back multiple characters from the dead, making the show seem unrealistic. In episode 7, Troy was revealed to be alive, and in episode 8, Charlie, who was thought to have died due to radiation poisoning, also returns. These resurrections are unrealistic as the characters should not have survived their injuries. This is not the first time the show has brought back dead characters, such as Madison and Daniel. Charlie's survival is explained as being cured by PADRE's radiotherapy treatment, but she ultimately sacrifices herself at the end of the episode.
