So No Head?

like during the LoW they’re separated physically from the rest by ice mirrors:

during vote1 it’s a battle just between them as they shed previous pretenses:

during the reunion scene sasuke gets up close and personal with naruto and only naruto as he speaks to him more personally, and enters his headspace as well:

during the kage summit arc they go to another plane of existence to discuss their bond, where naruto’s feelings towards sasuke clearly parallel hinata’s feelings towards naruto during her Pein arc confession (which also raises another interesting point - because it’s very telling that those particular words were the ones that were ‘hidden’ from the other characters): 

again during vote2 it’s just them, all outside interference stopped in its tracks. even kurama is asleep during sns’ emotional reconciliation in 698.

when sasuke leaves the village in 699 he leaves kakashi and sakura behind at the gate much like he did when he left in part 1, when he was able to break off the bond he had with them that night. but it’s naruto who comes to see him off outside the village (also reminiscent of part 1 - the one bond sasuke couldn’t break). their separation is between them alone, as sasuke takes the headband which has become representative of their bond on his journey with him, keeping naruto close while he travels the world.
