The point of the scene was the tension between the two men, and there wasn’t even much focus on the nude zombie on the peripheral.
This definitely wasn’t the Walking Dead nude scene that most of us are probably going to remember, and it wasn’t Norman Reedus in the buff this time.
If you didn’t catch this walker in the episode, don’t feel bad.
If you knew the nude zombie was on the way — and Greg Nicotero did tease earlier this year that such a zombie was on the way — you might have known to keep an eye out for a corpse wandering around without any clothes.
