You know I much I love when Bleach ends up with these big happenings, like on the on the most Shounenone mangas (sorry, lost in traslation...in italian sounds really good!) of all the times. So...Grimmjow, that now is simply disappeared, ehm. Or something like "ohohohohohohohooohoh"  -> the power of love -> Orihime: "Ichigo, come back" -> he comes back and Ulquiorra beats him. Sounds good.
