But half the ideas you point out aren't ideas. It's you really, really over-reading that there is an idea here.
**** It is when the author introduces ideas with no intent on following through with them. This manga does that . . . A LOT.
Overthinking is entirely a reader's fault, and of no blame of an authors.
**** If what Analyzer said about Kishimoto saying NH was thought from the beginning it's true then NS was a big red-herring. Tho, recognising it as red-herring is also admiting how deceiving NS has been and completely understandable for any person to thought about it becoming canon.
All of this you said people do, you also do. I'll show you highlighting words in your latest post:
Number 2: Whether or not he planned them from the beginning really is solely provably by his own words (Which he says). You can then use the material to discuss at what point this occured, be it at their introduction, the end of part one, the middle, etc. I do believe he meant for these to be together at their introductions, but he was sold on keeping it they way he intended at the middle. Someone discussed how Kishimoto keeps himself flexible, allowing multiple options (I.E., NS), but when he was toying with NS, which a lot of us feel was the beginning of part 2, for him it didn't work, thus this revert to what he was doing originally, as such, the Pain Arc, and really the Itachi Pursuit Arc, as it is. Of course, without him confirming, its at best an educated guess, so its free to debate the exact points of the beginning and middle that this thinking of his occurred.
It's note worthing that the run towards of Sakura and Karin (Notably Gaara brought Naruto to Sakura), that they are both healers of their respective teams, Sasuke's new Team, and the New Team 7.If these two cannot heal them, then things are bad. I don't really see this as a Red Herring shipping moment myself, but it might have been colored that way to mislead as well. Shikmaru and Neji were obviously not meant as romantic interests, their moments were never colored that way. I'm not sure about this making sacrifices to get noticed, as her point of making sacrifices is about love, not acknowledgement.
The next part is speculation, do we state this is when the Author planned it to be that way (Chuunin Exams, speculated), or when they were decided on it (Thus the Pain Arc, speculated). The Proud Failure Speech is certainly a heart-booster that changes how Naruto thinks about her, and is certainly the root of an argument that Naruto did love her, but did not understand it sort of moment. The Pain Arc is another, where Hinata futilely goes to save him, out of love, and because of that failure, Naruto feels the worst he's ever had, and just gives in to Kurama, he doesn't care anymore. Either one of these could be it, but really, its speculation, as in the answer to the question really, is when the Author decides it in his mind.
I'll never state a bond is over another's, or that they are heavier than another's. The Entire Team 7 execution is flawed, perhaps because it was Editor and time constraint pressure when Kishimoto was first starting, and it never really gets much build up to show how Naruto and Sasuke were these great friends exactly beyond it being informed usually. Notably the Naruto Sakura part of this triangle suffers the least (But it still suffers from being informed, mind), in part because they are often working together. You can certainly speculate part two's beginning as it is was Kishimoto considering it, however.
SS makes sense because it was informed, and it was shown that was it was going to, in mostly in informed fashion. No other Sasuke X or Sakura X pairing has a foundation, really. We can discuss how it's not really well executed (Certainly up for debate!). NH was more displayed, a play to its narrative strength. It definitely makes sense.
His interviews really aren't contradictory, as they are saying the same thing. I think we can sum up the gist of them pretty simply:
I planned NH and SS from the beginning, but was opening to exploring other options, thought about NS for a little while, but decided on what I was doing in the middle. I did play with some Red Herring of Sakura with Naruto (Thus the chapters after the middle), but it was always about Naruto and Hanta getting together in the end.
There isn't any contradiction to this narrative. It would rely on something above not being true in a second statement.
I believe Relevant interviews are the 2014, 2017, and post Gaiden Interview where he talks about SS being planned at the start.
" I do believe he meant for these to be together at their introductions, but he was sold on keeping it they way he intended at the middle."
Speculated. And since this is a speculation, your theory has as much value as anyone here saying it wasn't. Thus, not really giving you a reason to try and contradict or "correct" someone that states it.
"without him confirming, its at best an educated guess, so its free to debate the exact points of the beginning and middle that this thinking of his occurred."
