27. Dr. Edwin Jenner
Periodically on TWD, the survivors arrive at some place that appears to offer actual hope for a better tomorrow – until those promises turn out to be inevitably empty. Rick and company encountered their first cruel mirage at the end of Season One, when they reached the seemingly safe, well-supplied Center for Disease Control. But after spending a little time with the CDC's remaining doctor – well-played by the spookily calm Noah Emmerich of The Americans – it became clear that the authorities would have no comforting answers, and no future to provide. The devastating letdown of Jenner set the stage for the many disappointments to come.
