On the topic of nudity, in regards to this episode, for a few seconds, I began to think about how it was portrayed here. We have nude Ruby, who's powerfully feminine and formidable fighter; heck, she just came out of a pit of fire. She knows what she's doing.
The other time we see nudity is with that cheesy '80s pinup in the militia's bunker -- a group of weak, willfully dumb, sexist manchildren who clearly have no idea what they're doing or what they're up against. Ruby's nudity could be about second chances, or her unstoppable nature, or any other reason. The pinup's nudity, however, was just straight up objectifying, with no real thought put into it. It's probably not intentional at all by the creators, but it was a good juxtaposition, especially since the show rarely features nudity in the first place, which is probably why I started to wonder about it. Even the sex scene in the first episode had clothes on.
Also, seeing Kelly, Pablo, and Fisher blow that Deadite away made me think about the diversity on the show -- it very much solidified that the current world was different than what we had seen in the movies. The movies had virtually an all-white cast, and yet with this lineup, we have a young angry Jewish woman, the cowardly but driven Latino kid, and a determined black female cop as primary heroes. None of them look like the action heroes of Ash's time -- there'd be more assured, stronger men, for one thing. Times are changing, and Ash is slowly getting used to it, in that he's getting more and more paternal with the gang. Indeed, that they fight a gang of racists -- and even a Deadite made from a racist's body -- continues with the series' theme of showing Ash's slow adaptation to the modern world (not that he ever would have joined up with the militia in the first place, of course. Even he's too smart for that.). This diverse group of 4 people outwit an entire militia stuck in yesterday, and make them see the truth of the world, as Ash explained to Fisher.
