Really got to question what you were reading all this time if you though this was going to happen? I mean after the ending and Kishi stating numerous times that Sarada was Sasuke and Sakura's child....explicitly, not even beating around the bush.
I'm not sure if it was intentional but Kishi certainly exposed some of you with that red herring....and even though it was obvious some of you still fell for it. The question of Sarada's parents was never meant for the readers. It was meant for Sarada. She's never met or can't remember ever meeting Sasuke, doesn't know anything of Sakura and Sasuke, she's essentially having an identity crisis. Didn't you listen to what Mitsuki said.
She jumps to ridiculous conclusions with little logical basis (is my father with the girl who has glasses, is Sakura really my mum) but its understandable. She's a 12 year old girl who doesn't know about the past and wants to know why her father is missing from her life and so jumps to these conclusions. Some of you guys really should of known better, since none of this applies to the readers.
