Best episode ever! Grimmjaw's Release looks just as cool as in the manga. The movements were so smooth and like said above all new moves isntead of recycled. <3 Grimmjaw.

And about the mask, Ichigo actually wants to fight this time. Most of the time he did it because it was neccecary. But now he wants to fight. Hollows are evil and fight alot too so I guess that would explain it. That his lust for battle fuels the mask somehow =\
