We all like to joke that everyone stopped watching “The Walking Dead” a few years in, but for those who actually stuck with the series, Rick’s exit did not go over well. In the ninth season, a seriously injured Rick blew up a bridge to help save his friends, seemingly killing himself in the process. But a character named Anne found him washed up on a riverbank and gets her pals to take Rick away on a helicopter to treat his wounds and take him to a safe place, leaving Michonne behind and thinking that her lover has perished. Many years later, though, in season 10 of the series, Michonne finds a pair of Rick’s boots and an old phone of his, realizes he’s still alive, and heads out to track him down.
