guys I have a theory about how kakashi got the MS.maybe madara realy is obito.maybe when obit/madara got the MS,automaticly kakashi got the MS too as kakashi has obitos eye.in confirmed 425 manga spoilers we see kakashi talking to his father and he also sees asuma,we know they are realy dead.but he doesnot see rin and obito. why?!!maybe because they are alive.rin just left the village and never came back.nobody can say she is dead.and obito may haven been saved by someone.who knows...otherwise I cant excplaing kakashi having the MS
