Ok lets start from the beginning:

God knows what the hell Mayuri was doing in his room but it looks he and Nemu was standing over a body. But I think he might be doing something to his zanpaktou.

I actually thought Soi Fon would be training with Yoruichi but I guess not. And of course Oemeda's not invited she would probably tell him he's in the way and call him names the whole time.

So the old dog is Konomura great grandpa!? Make him change Konomura, teach that old dog some news tricks.

The whole "you will have to say goodbye to your zanpaktou Zangetsu," is not what I think it means. Am hoping that it means that Zangetsu won't look like Zangetsu anymore. But we'll see.
