From the impression I got it was that the Espada are Vasto Lorde's and that means Grimmjow is/was a Vasto Lorde.

On the the Vaizard thing. You just know that with an attitude like that Hiyori is asking for beats, and she is gonna get smacked up one day and turn all emo because of it.

Maybe its the English, but what the Vaizard are saying seems contradictory. On the one hand they are saying that they will show Ichigo how to supress the hollow, and on the other they are asking him to pull it out. Is translation supposed to be 'control' and not 'surpress'?

The Kon part near the end was good. I don't even know what Kenpachi is going to do, though whatever it is it should be fun!
