I don't know how people here did understand the last chapter, but for those who're doubting about next SS moment without Naruto, here is an example how to read what happened.
First, you have to remember that a Kagebunshin user can't get information from his clone(s) before they explode. Very important to know in this chapter.
Now, let's start :

Obito tells Sakura and Naruto's clone to touch his body so they can jump into the other dimension.
Remember what Obito said before, this use a lot of chakra, Naruto's clone is here to give his chakra for Kamui.
This is Obito's trick to enter Kaguya's dimension.
Let's see what the real Naruto is planning :

He completely ignores Obito's plan. It's logical, cause that clone with Obito didn't dissapear yet, so he can't get information yet of what he's planning with Sakura and his clone. That's why, Naruto try to find his method for getting there, where Sasuke is supposed to be. He knows, he can sense his chakra, he's still alive.
Naruto: I'll look for Sasuke.
Real Naruto want to save Sasuke "alone".
Now, to enter Kaguya's dimension, Naruto has to force her open the gate.
Tajuu Kagebunshin is used for that.
Then :

Pay attention at this, it's very important.
Real Naruto says in his mind, that he's the real one, and that he will enter.
What happens next?

Kishimoto is trying to tell us that this is real Naruto, that Naruto we saw enter her dimension on page 12.
Zetsu is sure that this is his real body, and that clones aren't able to jump trought space cause they don't have enough chakra.
So Zetsu convinced Kagut to kill him, cause it's dangerous to let him stay in that place.
And that's when it becomes interesting.
When Kaguya returns to the Ice dimension, the clones didn't dissapear.
Wich means that Naruto tricked them and made it.
How? That, we don't know yet, but it's obvious that the real Naruto we saw on page 12 wasn't the Naruto that Kaguya killed.
We know that Naruto is an unpredictable ninja, so nothing surprised me.
Maybe a henge jutsu? I don't think that neither Zetsu, Obito, can sense tools.
This is one of Naruto's speciality, remember Zabuza's arc?
So, don't listen to SS fans who are expecting Sakura to be alone with Sasuke, it can happen, but it's not sure.
