Only Shion is not cannon, right? ;) And that scene with her at the end of the movie was purely for comedic purpose.

With Hinata I will know for sure when I see the movie, but from this glimpses I saw it looks like Hinata just couldn't tell Naruto about her plans because well, if you want to trick someone it is usually not wise to explain everything to other person when the one you want to trick is right there. And from spoilers I understand that it is something she will come up with during mission, when rescue team get ambushed.
