No, everything is clear in this chapter. Sasuke wants to shoulder everything on his own. JUst like Naruto did. That's why he had those flashbacks.
alright. you said naruto carry thing all by himself.
think carefully, do u think naruto able to understand sasuke pain without some of the itachi guide?
do u think naruto can beat sasuke without portion of all tailed beast chakra inside him?
do u think naruto able to go this far without people from the pass keep guiding him?
now i will explain,more,
in naruto dream he has many friend including sasuke.
in sasuke dream. he having himself. solo king.
naruto not shouldering alone. all tail beast gonna shouldet together with him
ps dont judge with only 1 chapter of manga.
naruto coming all this way because he is not figthing alone.
when vs pain, he has frog helping.
when vs obito, he has sasuke, shinobi alliance, tailed beast even sasuke.
when vs kaguya, kakashi, sakura,sasuke.
naruto is not shouldering thing himself.
anytime, anywhere, theres ppl supporting him behind.
