zangetsu in bankai mode look so young and powerful 

I wonder what tensa zangetsu meant when he say he cannot teach ichigo because of protecting something 

what could it be??

Aizen got stab by a mere bankai..   he'll be a sore loser if he fall down just like that. 

Aizen make a big mistake by telling Gin his zanpaktou weaknesses. 

If Aizen died, then he can join tousen in hall of shame - worst die in bleach arc category.

There better be a good explanation on how Ichigo manage to power up in such a short space of time and matched Aizen's godlike powers
