This are some very important questions left unknown and im just helping you guys remember it.

Where is Yamato? When/why did Obito go to Kiri and control a Mizukage? Who is "the one who knows everything" that Sasuke's searching for? What's in the scroll Suigetsu found? Why doesn't Obito use any rinnegan techniques? Where are Naruto's comrades that were heading towards him? Why isn't B doing anything anymore? ...Yeah, there's a lot more questions.
