Sasuke chapters with Sasuke aren't the problem. It's Sasuke chapters with Juugo, Suigestu, and Karin. Those other three make it feel like filler. Kishi wasted way too many pages on their nonsense. And sadly, those two clowns are going to be allowed to be lap dogs to Sasuke again because of that Orochimaru scroll. And Karin will also find them.
I am curious to what is in the scroll. I feel it is something we haven't seen before. And will allow Sasuke to be a factor in the war. At worst this allows Kishi to pad the manga some more.
Could anything come of Sasuke vs. Itachi? Just more talking. Sasuke is not going to change and probably will support Itachi defeating Kabuto. And Sasuke vs. the K12 is now pointless because he won't kill anyone until Naruto.
