In the previously aired Season 19 Episode 442 of "Naruto: Shippuden" we saw Sasuke training to become a powerful member of the Leaf Police Force in order to defeat Naruto once and for all. He has now returned and will be seen fighting Naruto in the upcoming Episode 443 titled "The Difference in Power".
However, it is not going to be as easy to defeat Naruto as Sasuke hopes for it to be, because the young ninja has also been training in anticipation of facing off against his former team-mate. Jiraiya had made him realise in "The Mutual Path" that Sasuke's request to move on to Leaf Police Force proves that on some level he is aware of Naruto's strength. However, he is training to be better and Naruto should do the same, if he wants to stand a chance against him.
He therefore leaves with Jiraiya to train, as the teacher leaves to find out more about Orochimaru, who as we know has promised DanzÅ a young, strong body in its prime, in time for his next shift. Naruto's friends of Team 10, along with Kushina, Minato and Sakura sends him off, as they too swear to train and become ninjas.
Sakura, the other member of Team 7, is disheartened by Sasuke and Naruto's decisions to leave the team and decides to train under Tsunade to learn the Reverse Seal, so that she is not the only one left behind.
Konohagakure's legendary Sannin Orochimaru and Itachi, meanwhile, have accepted Minato's mission for Uchiha and would likely be keeping away from his family, seeing as the mission is long-term. He is the one person Sasuke unconditionally listens to, and if he is caught up with more pressing matters, Itachi will not be able to stop his brother from fighting Naruto.
However, these are filler episodes, and the consequences of these dream sequences are not dire. "Naruto: Shippuden" will return to the main story in 2016.
Watch out for Season 19 Episode 443 of "Naruto: Shippuden" on Thursday, 24 December via TV Tokyo. You can also live-stream "The Difference in Power" via Hulu (United States only) or Naruspot.
