AMC's The Walking Dead celebrated its 100th episode with a series of callbacks to the first episode, "Days Gone Bye." The show's success led to a total episode run of 177 by the time it ended in November 2022. The 100th episode, titled "Mercy," recreated many shots from the first episode, including scenes with a returning zombie actress and actor, and a parallel shot where Gabriel hides in a trailer as Rick once did in a tank. The callbacks paid homage to the show's origins and marked a turning point for its characters.
