You Know, when I think about it, I really was kinda sad to see Stark go, but not because he had some sad sobby story, but because he really wasn't ever truly a bad guy. Contrast that with Number 10/0 who was just an oversized thug.
I'd also say I felt a little bit sorry for Number 4 when at the very end he began to realize what it meant to have a heart, Inoue reached him too late. Now Grimjow (6), Szayel (Number 8) and Number 5 Nnoitra, I was just too glad to see them defeated.
Now, who here didn't enjoy seeing Ichigo shoving old Aizen's head into the ground?
Regarding Next Chapter:
1) How they get back to Byakuya
2) I suspect that the Old Guy is not fully dead even though Kenpachi cut him in pieces. I think that his Fullbring, once activated is probably going to do what it does, regardless of the old guy being around. Question is whether it had enough time for activation, and whther Kepachi's Reiatsu will be enough to quell whatever it does.
I am not perfect and I defy you to prove otherwise
Growing Old Gracefully is an Oxymoron ... Mostly Moron !
