While there are many loose ends and questions one is really bugging me at the moment. Who the kitten did sasuke sense in the end of chapter 700? Lol watch them use it for part 3
I think it's more of a comedic effect to be honest. Sakura and Sarada were talking about "daddy" and he probably sensed it. Kind of like that myth where if someone is talking about you, you sneeze type of thing.
