Just remember, this is stuff made for middle schoolers, it is not overly complex and hard to figure out.
She was suprised for the most part, that Sasuke is working with them but as others have said too, Jugo is speculating that there is something else to Sasuke's motives.
If anything is bound to be a focus for the next chapter or in a few, its Jugo's comment. This whole ending to the current chapter is more or less just going to be disregarded and just move forward with the story. If anything is notable for future chapters like the Sakura=Kushina parallel of 631, its this, Jugo's comments and Sasuke's true motives. Sakura's power up was a short term speculation, we got it, now they are moving forward.
Team 7 is simply fighting back to back, all 3, its not just Sasuke and Sakura as some twisted it, Naruto isn't being ignored, its not payback at him for "ignoring Hinata's feelings by calling Sakura his girlfriend," its not Sakura reverting or fangirling, its not a trolling moment like 615 which some set their hopes insanely high for. This whole thing just gives new meaning no need to make a mountain out of a molehill.
Guess this means if we get a moment next chapter with Sakura just being amazed or acknowledging Naruto's current action, then we should make a big holy deal out of it right? It happened, it passed, its done. Next thing you know, this stuff won't ever come up again next chapter and we will talk about something new even if its minor. Not every interation means a pairing moment, this was in no way a pairing moment, as said before, what does it accomplish? The Sakura-Kushina and Sakura's power reveal still outdo this thing immensely, 615 we had reason to be concerned, not anymore with it. We have no reason to be concerned with this, so until next week, people should not be picking at these holes, there is a very simplistic thing here, its just a simple reaction and then she talks to naruto, as Sakura said to Naruto its like people both pro and anti NS should do, stop making a big deal and don't fret over the little things, its not a concern to us in anyway, its not going to harm us in anyway, and for the haters, its not going to carry on, its not going to make any difference no matter how they try to dissect it. Sakura was still focused on Naruto for 630 and 631, 632 she was speaking to herself and if anyone both her teammates equally, she spoke to Sasuke and had a small prank on Naruto and told him to not worry, thats what everyone should do. Otherwise every little NS interaction we see in the buildup thread would make NS canon by now. Sakura is fixiated on Naruto a lot, she is not going to revert or abandon Naruto no matter what others say. So there is no need to get a big deal over this again.
I'm assuring everyone here, if we get a NS moment next chapter too, just watch as its completely fine, this stuff is not going to come back and its really just silly to make a big deal out of it in the first place, one little Sasuke-kun and Naruto complaining, and the fans being unsure of her reaction being blush or dirt, who cares at this point? Does it really impact what we saw in 631? Sakura=Kushina is still more important than a silly little moment like this. Even if we jump back to kakashi and obito or elsehwere with orochimaru and taka, its not going to matter by wendsday. Now I'm going to enjoy my weekend, I've still see enough that this will not matter by then. This whole matter of worrying over a little Sasuke-kun, its just too funny and not worth making an argument out of for both the pro and anti NS. We are fine, we have the advantage. SS and NH have a lot to do in order to get around the Sakura-Kushina thing.
To me all this fuss dies right in the moment 632 ends, as Sakura said, don't worry about the small things, she was already addressing Naruto's I'm here too statement right there. Its done, its over, now let us kindly wait for 633,I sense a forehead compliment scene in a future chapter. Maybe a minor NS moment in the next chapter, I mean its highly likely.
