You can try, anyway! Because if the problem with those theories about the secret of Sarada's birth is that they don't make sense, keep in mind that the secret of Naruto's birth didn't either. ^^
Sarada's the lead this time around because this just serves as a prologue to the upcoming movie. She'll be useless when it counts, don't worry!
I'm glad she's getting 13 chapters to herself. So far it's kind of fun, I wonder if Sarada and Chouchou are going to get an action scene next chapter.
