I found a nice picture showcasing the most important characters involved in the plot.
There's just one problem (clears throat):
♪One of these things is not like the others,
One of these things just doesn't belong,
Can you tell which thing is not like the others
By the time I finish my song?
Did you guess which thing was not like the others?
Did you guess which thing just doesn't belong?
Then you're absolutely...right!♪
hahaha lol
Singalong .. 
OT: If the 645 prediction comes true than fans from the opposite camp will be a little disappointed it ended so early including myself ( c-cant help it , i like tension
and suspense) ..
IT should end when Sasuke is redeemed and SAkura has the right to choose and here is my reasoning for it .. I've been on the anti -NS tag ot tumblr ( yeah im that kind of an idiot
) so I've read that Sakura will choose Naruto just because and i quote ''SASUKE IS EBIL!'' ...
or she ONLY punches NAruto and never did with Sasuke SHE LOVES HIM''
.
Any previous interaction between them or development does not matter , Sakura's hinted feelings through out the whole manga remain silent and left in the black?
Sometimes this side of the fandom makes me charge running against a wall ...
Back on track , so just to shut them up Kishi should do it like that , but there is the other thing Sasuke won't be accepted back in the village that easy , he wants to be hokage which wont happen not in a million years and there you have the Main conflict ... He will demand the seat to rule , but he lacks acknowledgment from the villagers including the jonnin and dimao, which will lead to his second defection and betrayal .. Now what could happen then? Naruto goes against him , he told him under the Samurai bridge ''If you come to attack the leaf , i will be there to fight with you'' and he forbid any of his friends to interfere , but will they listen , will Sakura sit in the background with her legs crossed drinking cups of tea and thinking '' Oh , i don't care what happens'' , NO that we can guarantee that won't happen.
She and the others will want to fight and to retaliate , because lets face it everybody loves Naruto (especially a special pink haired chick...
) , so no one would stand around and watching him get hurt,carry this burden on his own which again brings me to the Samurai bridge , didn't Sakura and Kakashi both wanted to ease Naruto's burden? Mainly Sakura , so that brings me to think that those two will play a key role in the whole Sasuke thing..
It is not really believable that Naruto will fight alone..
