If a jet is flying Mach3 towards you and you can track at 300,000 frame per second. Just because you see it coming at you from a distance in slower motion doesn't mean you can GTFO the way. Simply because the Byakagan can track it doesn't mean Hyuuga >
The only thing Lady Byakagan is saying is Hinata saw the Juubi being sucked in at slower pace than what actually happened. EVEN if she is right what's the big deal?
