@olayans No you're not crazy, you're just over thinking all of it. Most likely this entire thing about Karin being the mother will lead to nowhere. Unless it really does lead to Karin being the mother meaning she is the one that actually gave birth to her, and this is Kishi's way of destroying SS. Problem is it's destroying Sakura's character even more by doing this. And Sasuke's character and Naruto's and everyone's.
It's just making a bigger mess than it already is.
That's right, if Sarada results to be the daughter of Karin, Sasuke's character will be destroyed and Kikitten won't allow that =_=
