Why wouldn't he have the stones after all this time. The manga is over so he could **** on this character like he has the entire manga.
Him making Karin the mother is just his way of putting blood lines together not who should be with who because they look cute together.
(in my opinion)
It's about bloodlines people.. it always has been. And where does Haruno fit in those dominate bloodlines.
All the promotional crap after the original series wa sover with it stating sakura as the mom and the fact that it's kishi, i think it 99% sure Queen sakura is the mom.
