Last reminder: Naruto happened.
That's why everyone is believing these spoilers. Forget about pairings for a second, the whole chapter left all the biggest questions unanswered, and showed Chad doing something we know he can't do. Also the RenRuki's baby name can't be right. All of this, but we know we can get this from Kubo, because for the past few years he has been inconsistent with canon. Chad hates hurting butterflies and wouldn't use his fist/power for self-gain? Let's make him use his fist/power to hurt people for money and fame. Uryuu, make him what he hated too. Uh, they need a Soul King to live? Nah, screw canon, I can't give them 1 panel of a guy frozen to show them who it is. It sounds like complete garbage, but what have we been getting from Kubo since the Ichigo vs Aizen fight? It sure wasn't all garbage, but these last 20 chapters have been.
