Great info! Glad to here Gin is dead. Aizen still being used was kind of obvious, but nice to have proof. Not to sound like a speculator, but Grimmjow appears to be back. It has evidence in its favor. For example, he is alive. Secondly, Ichigo (correct me if I am wrong) said this to Urahara when Ichigo was in Soul Society and Urahara was in Hueco Mundo (Chapter 518): Why are you with "him?". Also, you could see the lower torso of the person. It has to be either Grimmjow or Gantenbainne Mosqueda, who Ichigo never met. It could be Dondochaka, but that would make no sense. All things point towards Grimmjow.Any body have a counter example? I could be crazy here.
