THIS!About confusion: Samehada is obviously with KB, KB says "he forced you" to the sword; meaning that sword was forced to cooperate in Kisame's deception. And sword leaves Kisame on its own will, as you can see that Kisame is surprised. Samehada goes to KB because it loves him (lol), but then is forced by Kisame again to absorb KB's chakra.
Naruto out of the fight ?: Naruto first getting his foot stuck in the floor, hurting his ankle is indeed "lame". He is all powerful having his own power and kyuubis power (which both are monstrous), but somehow he can't pull his foot out from few inches.
And he has this divine healing ability coming from fox chakra which he can easily heal even tho it shouldn't have been hurt in the first place. He can also use SM chakra to heal it in the same amount of time which Yamato wrapped up his injury.
Its too obvious this was a forced event to make Guy fight Kisame alone. There could be a better reason made up to put Yamato and Naruto out of the fight.
But hey, its still good to see other ninjas such as Guy in action. Naruto may be the protagonist, but story is only fun if other people aren't left out to be shallow and fading.
I agree totally... And thank you for mentioning the fact he needed help pulling his foot out of a wall... I wanted to bring that up on the last chapter but forgot... It was a really poor excuse to be excluded from the fight... and just makes Naruto's new powers seem abit lame!... His Kyubii form would have ripped the crap out of that wall like butter... It seems abit of a contradiction! :/
