theory to save kakashi!
This is a long shot, and i mean a LOOOOONG shot, but bear with me.
Even if i get 50 replies of "no", il actually agree and wont care LOL, but ive got an idea that would be cool to save kakashis life.
So naruto doesn't know konoha is being attacked
and naruto is the only one who could get close to pain now kakashis gone because hes learnt many of jiraiyas moves, and he has pa toad to do the intellectual stuff for him as well, naruto is good at fighting, pa toads clever.
Anyway, kakashi is on his last legs, no chakra, god pain's still alive (and in full health) and can own kakashi in an instant now his chakra is 0, even kakashi himself is simply accepting death, usually hes got a last trick, and he doesnt, hes used it already.
So, pa toad starts teaching naruto flying thunder god technique (yeah, like i said, LOOOONG shot)
Pa toad places sealed kunai around the place for naruto to practice.
someone had a theory kakashi MAY still have that old kunai the 4th had (old thread someone made pointed it out, but theres no reason he wouldve given it back)
I think kakashi may always keep it as a reminder, and a momento kind of thing.
Anyway, as narutos training and having difficulty maybe, he stresses out, uses a buttload of chakra, and teleports directly next to kakashi whos about to die, and naruto lands a can of whoop-ass on pain.
Looooooooooong shot, but wouldnt that be pretty cool?
