Since the writers of The Walking Dead have hardly distinguished Beth (Emily Kinney) from other seemingly zombie-bait supporting characters over the past three seasons (the lone difference being that she’s survived over that stretch), her opening monologue that kicks off “Inmates” is somewhat of a surprise. Her voiceover, from a diary entry written before the prison’s destruction, expresses her mild hope in the stability the survivor group has achieved at the compound. This kind of emphasis on a relatively minor character typically hints at his or her demise. And as if that weren’t enough, the accompanying imagery of her and Daryl’s (Norman Reedus) exhausting tribulations in the walker-infested forest is strikingly ominous. However, the episode doesn’t deliver on its portent. In fact, the last time we see Beth, she’s weeping over several mutilated corpses next to a railroad track. The episode returns to this location again, but Beth and Daryl’s journey will likely pick up in coming episodes, as “Inmates” takes shape rather unexpectedly, with four short, open-ended vignettes following different groupings of characters that made it out of the prison.
