Yes, but ask yourself this: from the writing POV, why did Kishi have Hinata be the first one to hold Naruto's hand? Why make her scene the most important one, the one that lasted the longest? Why isn't it Sakura in Hinata's place? Why wasn't it Iruka or Shikamaru or Kakashi in Hinata's place? Kishi wrote Hinata to desire to hold Naruto's hand for a purpose and he did have her hold Naruto's hand for a purpose, too. Maybe that purpose is just to complete Hinata's character arc, as you all say. Or maybe it did hint at future NH canon. We are still at the same point than we were after ch 615 came out: we still don't know how Naruto feels about Hinata or about Sakura and are back to arguing about the handholding.

So maybe we should let that matter rest for now and discuss other things about this new chapter. We are not going to move forward at all in this handholding thing. Only the future chapters will tell us which one of us were right.
I think those are totally valid questions. And it's completely worthwhile looking deeper and questioning why one character over another. No matter what the ship. So for me, the answer I come up with is that Kishimoto did it to ramp up tension in the story. By really giving one pairing a boost, he reinvigorates the story and interest at a point when it could become very bland. Just straightforward fighting.
Honestly, I don't think anyone really cares if Naruto redeems Sasuke or not. We all know he will. No real suspense there. No, this was inserted now, so the audience can think about the end game and wonder what their favorite characters are actually fighting for. Battle scenes slow down plot momentum. Inserting the love piece brings value to the fight. Whether you support that ship or not. So to me, it's about ramping up tension.
NH now has real legs to stand on. And by pushing forward NH, then he tacitly imples SS. So it reinvigorates the story. Nothing is decided, everything is still up in the air.
We were all waiting on tenterhooks for this chapter, right? As were the NH-ers and SS-ers, right? So then...mission accomplished. As an audience, we are now reinvested in the story.
lol, MS... I checked on 2ch now about Ohana's script (pretty accurate from the original)
she written: "小娘" which means young girl so Mangapada was right here.
anyway madara doesn't gives a damn about this, he's just... Madara xD
hahaha! too true! thanks for looking at that!
