My Prediction for 420
The chapter opens up to Falcon
Karin: What now?
Sasuke: We go back for Suigetsu's sword and then we go after the swordsman under Kisame.
Suigetsu: There are only 2 them still living. The other five are dead.
Karin: Why are we going after swords?
Sasuke: !!! Everyone watch out!
Falcon scatters, the earth sprouts massive thorns of earth.
Light Zetsu: Did we get them?
Dark Zetsu: No.
Madara appears with the EMS activated.
Sasuke grabs his sword and stares back..
-- Scene switches --
Naruto is surrounded by boulders, he goes into sage mode and thrusts a single palm at each boulder creating a huge gust of wind to shatter the boulders into tiny sediments.
Pa Toad: Pretty good, Naruto. *Pa toad waves his staff causing more boulders to erupt from the ground.*
Naruto jumps into the air and does a few handseals. He blows a powerful wind from his mouth and shatters all the boulders leaving a small crater in the earth. Naruto lands on his feet.
Pa Toad: Excellent job Naruto.
Naruto: Uhh. This Pain guy, haven't you fought him?
Pa Toad: Yes. He is a very powerful overwhelming opponent. He was Jiraiya chan's former student. He possessed the Rinnen'gan and Jiraiya thought that he was the child of prophecy. Jiraiya said this student mastered all five elements. A ninjutsu master.
Naruto: !!! *Thinking wind won't do good enough against fire.*
Pa Toad: Naruto. Now it's time for you to learn your second element. By using Sage arts it'll be more easier to recompose the element.
Pa Toad hands Naruto the same paper Kakashi handed him.
The paper becomes soaked.
Naruto and Pa Toad: !!!!!!

Fat Pain: You're a pest. Fat ass.
Chouji: !! *Turns around, Fat ass?!!!*

Chouji is enraged.
Fat Pain: .....
