I can honestly say, that with that 667 hint/spoiler, I would love for the chapter to go that direction.
I would love for Naruto to get one last time with Jiraiya (although I think it wouldn't do any good for the manga and frankly, I'm just too tired atm to see how it would tie in).
Naruto & Jiraiya scene. Naruto wakes up, & we all get the long awaited Narusaku forehead scene with a big, wet and sloppy
make out sessi- Confession.
but meeting the Rikudo Sennin is fine too. I just want my ns scene so that my heart can explode after Six Hundred and Sixty-six chapters. LOL
Edit: Typos
It is okay to expect a moment but dosen't it sound a bit absurd that protagonist has just cheated death, there is a war going on right now, they are faced with the most badass character of all times and what they do is confess their feelings for each other to their heart's content in the other dimension?
