It is just something thats randomly thought up, and had fun with. I did so some research by reading back on the manga to make sure of a few parts. Enjoy. It's something.
As Kakashi and Obito prepare battle, they land in a area where they have no recolection of.
Kakashi: Where are we?
Obito looks at Kakashi with so much anger, he doesn't really care if hes lost. He just wants his revenge.
Obito: *Fire Release*
Kakashi: *Falls back, and just barely manges to dodge the attack*
Obito: *Goes over to Kakashi, and picks him up by his shirt where Kakashi is dangling off the ground.* "Tell me. Why did you kill Rin? What did she ever do to you? She didn't deserve to die! It's your fault! *Throws him on the ground*
Kakashi: Because she asked me to. Her body was taken over. I had no choice. She could of caused a lot of deaths if she wasn't killed.
Juubi still continues to wreck havoc on the battlefield, leaving the Shinobi hadly any time to launch or dodge any kind of attacks. Any attack they try to launch, is useless against the Juubi since he is so powerful.
Madera: *laughs* You can't defeat me. You can't destroy the Juubi. You will all die.
Scene changes again

Tsunade is not responsive.

Minato: Naruto, hang on! We are on our way!
