Trivia

 * A few photos were leaked online that showed walkers outside Woodbury which means that a group of walkers could attack Woodbury though this is unconfirmed and purely speculation as it is unknown what episode the photos relate to.
 * The title may refer to the previous episode's ending when a group of walkers, together with Michonne, arrived at the edge of the prison. It could also refer to walkers that were seen approaching Woodbury, or possibly tease that Michonne may go back to Woodbury as she is presumed dead there.
