So there was one panel in chapter 690 showing Kakashi grabbing Sakura to escape danger. Last we saw she was pounding Kaguya right next to Sasuke and Naruto, but its always Kakashi who somehow ends up at her side.

And he showed concern about her in chap 679 thinking "those two will certainly be okay, more importantly, Sakura! don't be rash now."
This is the LAST battle to save the world. If Kishi planned on a NaruSaku or SasuSaku, now would be the time to do something right? I mean, I know Naruto and Sasuke were busy, but when Naruto yelled at Sasuke to save Saku
