episode of the season. The episode marks the final appearance of recurring character Joe (played by Jeff Kober) as he was killed by Rick Grimes by biting out his jugular vein. The scene where Rick, Michonne and Carl are captured by Joe's gang was intentionally shot and produced to follow a certain portion of the plotline in "Volume 10", "Issue #57" of the comic book series. The main difference is in the comics, Rick, Carl, and Abraham are captured by three bandits, whereas in the show, Rick, Carl, and Michonne are captured by Joe's gang of five men.

Writing for Forbes, Allen St. John, commented the finale positively, saying, "This episode, directed masterfully by Michelle McLaren of Breaking Bad fame, puts The Walking Dead in an interesting place. The story line takes our heroes into a dark place—and what can be darker than a locked railroad car?" IGN's Roth Cornet rated the episode a "Great" 8.0, writing, "The Walking Dead Season 4 finale served as a response to a question Rick has been asking himself nearly since the start of the series: What kind of man am I? The answer, at least to some degree, is whatever kind of man the moment demands of him; which is exactly what he’d need to be in order to make
