SS is agonizing ^^, some fans still believe Sasuke is good has feelings for Sakura and NAruto will fall in love in Hinata buuuuuuuuuuuuut its quite the opposite, right ?
Opposite indeed.
SK is the only pairing I still wonder if it will be canon.
I think the rookie ships (Leeten, Shikatema, Chouino etc) will just be shown in an epilogue or and open ending, because they are side characters.
But Sasuke is a main character. It is important to give closure and tell what life he'll lead in the end. Personally I think catsi563 has a good point, that Sasuke will switch places with Naruto and build his bonds all over again.
True, but sometimes if not most of the time, second main character don't really show a lot of romance development time or conclusion. It usually leave you with a good pairing moment, then epilogue handles the rest. The protagonist is the one to get the moment of shine on-screen. It's just the one we care for the most, like it or not.
If she doesn't know about the plan then she'll be surprised or something, but I don't think she'll have something to do here other than that. Pretty much, she'll be like the other Takas if they don't know either.
But, if they don't know, they won't just say " Okay, we'll follow through ". They'll follow him with what he'll do, but it's more right to do it within that they already know like it's easier for this situation.
Refresh my memory, Juugo said he doesn't know, or he didn't say anything when Sai asked him what's Sasuke's plan ? So, if he doesn't know then all the others don't know, except maybe Orochimaru, which say that Kishi will make them surprised or something else.
I think if one side character won't be shown paired then he won't show all the other side characters paired. We'll see XD
I believe Juugo knows the intention, but the plan as in the setup is something he don't know. Orochimaru is doing the plan setup, but he doesn't know the main point of it yet, though I could be wrong. It's interesting that he didn't say it out loud that he's waiting for Sasuke to unleash his "wind". So pretty much, Sasuke is in fact planning to do something but right now, eliminating the enemies.
