I thought this was an excellent chapter. What I love about Sakura's role is, unlike Naruto and Sasuke, her contributions are not godly, and therefore it feels like everything she does has risk and effort. When Sasuke and Naruto spout their jutsus, I don't get that feeling of limit, or that what they're doing requires a massive amount of work. They just spout off their ridiculous abilities like a fountain spews out water. For instance, Naruto and Sasuke both did something this chapter. Naruto managed to 'make it' and not die, and Sasuke teleported. Yet none of that was as exciting as watching Sakura push herself and deliver chakra so they may open portals to reach Sasuke. It was a joint effort with Obito to be sure, but I see it as Sakura doing the bulk of the work--she's the one providing the juice to make this possible.
I've never considered Sakura to have so much chakra before, and now I can see what storing it for three years has done for her, and she's also contributed to the war effort before this so it's not like she was working off peak ability. For someone who is not the cosmic descendant of a major goddess, that's really impressive. She's human, and she's never gotten a hand-out like that yet look what she can do. Even Kakashi had the sharingan. Let's not forget that Sakura had nothing. Her parents weren't anyone significant. She was not born with any special ability that has been highlighted (I dunno if they'll reveal something in the future about her Inner self or whathaveyou), she was just really smart and applied what she learned. There are few other characters like this in the series, yet look what she's doing now. Kakashi is seemingly out of the picture without the sharingan. It's true that Sakura can't do without the help of people around her, but being able to help and contribute something despite being so ordinary makes her extraordinary to me.
However, I wonder what the significance of losing her clothes may mean for her in the future of this fight. I don't consider it just fanservice. Kishimoto has highlighted her vest and her headband. Is it a sign of the threat of her mortality? Like, every bit of this fight takes bit by bit away from her. Or is it a sign of transcendence, where she's losing the things that define her as a 'shinobi' and making her something more? I don't know, but something about the sight of that burnt vest--the very last panel of the chapter mind you--is a little foreboding to me. I'm not going to lie, seeing what happens with Sakura (not NaruSaku) is what's pulling me through this fight. It's what I look forward to every chapter. I have no shame admitting she's the most interesting, compelling aspect of this arc.
I don't really enjoy how it seems Black Zetsu is the one calling the shots, and figuring things out. Kaguya feels like she's being manipulated by him. I want to see her taking initiative, or else she doesn't seem as threatening as she is. Maybe that's her downfall? Her weakness? I don't know, but as long as Black Zetsu is talking in her place Kaguya doesn't feel the threat she is, maybe because despite her power it feels like she can't think for herself, and thus will make mistakes. Or that she'll be overpowered by the thing that calls itself her 'son'.
As for Sasuke... I try to not respond to outbursts of SasuSaku fear; it just seems rather silly to me. So instead, I'll talk about my interpretation of what the scene is, take it as you will. I think that what's happening in the scene is a reconsideration of Sakura's role. Sasuke had written her off as someone who may as well die. For him, the only real players in this were himself and Naruto. For all he thought, Kakashi, Sakura, and maybe even Obito were just people in the way. The fate of the world depended on him and Naruto alone. Yet, they got seperated, and for a moment that could have been the end of humanity. Sasuke couldn't get back to Naruto, and I don't know if he knew that Naruto had it in himself to get to where he was--so without the two of them to seal it, it may all be over. Yet, Obito with no understated measure of Sakura's help, managed to find a way to reunite the two that could seal Kaguya.
Sasuke catching Sakura could be because now he sees the value of having them as allies. If something goes wrong, it may be in their power to help. In a fight where all of humanity is at stake, that could prove the difference between win or lose. Now, rather than letting her fall (like he would have few chapters ago with his hawk), he catches her. That's a sign in a shift in attitude. He may consider them worth saving if it means they can be of help getting him back to Naruto. The eye-contact I see as a sign of their former teamwork. There was a time when they meant something to each other, as friends. Sakura showing her power could be a moment where he looks at her, and really makes me wonder what they're thinking. Their relationship is forever changed, and I think it leaves them in an odd position which is why they made eye contact so ambiguously. How does Sakura feel? How does Sasuke feel? It's so uncertain. Which is exactly the position they're in. Friend or foe? Ally or not? That's why I liked that panel. You can't really tell.
