Yeah,i noticed that ,as well.Though,that moment was really awesome :ls:
i am wondering myself but it was epic moment
I think it was his young voice and his current voice at the same time
So basically its obito's young voice and adult voice at the same time?Oo
first voice = his own voice.
second voice = Madara's voice (the one he faked as "tobi").
I guess it's just to show his 2 personalities: "fake Madara" personality and his own.
