Does anyone else know if Grimmjow will make an appearance again other than his "return"? And why was he NOT going on a killing spree and trying to axe-murder everyone? Did he make some sort of agreement/deal with Urahara that we don't know about?
Also, who else thinks it's cool that the guy that Ichigo knew as "Zangetsu" is actually Ywach? It blew my mind when I discovered that. Which makes me wonder... what is Zangetsu's true manifestation?
