Ok, so I read several spoilers about Naruto 486 last week and one of them really made me think about something. Now with Naruto 486 released, I think my thoughts could actually become reality. What I read was this sentence: "And we'll die together!" (Naruto 486 Page 13)
Ok, so a lot of people immediatly started thinking that Naruto is gay. I, unlike those people, was thinking what kind of meaning this could have.
Now I'll go back 116 chapters, where Jiraiya is talking to the frog with the seal. (Naruto 370 Page 10)
At that page, Jiraiya says that he believes that Naruto is meant to complete the sealing technique used to seal the kyuubi (Shiki Fuujin). If you read one page further, you see that the frog with the seal doesnt think Naruto is ready for this jutsu yet, since he is not able to control the Kyuubi inside him. In other words, I think Naruto will first undergo some kind of training to control the kyuubi (Killerbee will probably be the one doing that, could become quite hilarious tbh), which some people might have predicted already. But I think after that, Naruto will learn how to use the Shiki Fuujin. Personally, I hope/think both Naruto and Sasuke wont die, but if they do like Naruto said, I think it will be because of the Shiki Fuujin (Maybe Naruto will meet his dad after that again, who knows).
Anyway, just wanted your thoughts about my theory.
