I don't care whether this thread has been done or not so here goes. The ANBU or hunter nin from Kirigakure where saying to Obito don't underestimate the "Bloody Mist" referring to the time in which Obito or Tobi was controlling Yagura the 4th Mizukage.....? So Obito started the hidden mist as an adult..... and is a kid fighting bloody mist ninja . This chapter has more unanswered questions than anything. Its safe to say this chapter confirms Obito can time travel and Obito went back in time to the period in time to control Yagura and start the bloody mist to get revenge on them for killing Rin.
