Ressurection is all espadas ability to release his Zanpakutō , i think it has a different name from an arrancar's release since its so much powerful .

I actually kinda liked this episode since its the first time rukia "kicks ass" :P and to an espada even. Can't w8 to see what the hell renji is gonna do besides getting owned lol. Also next episode ichigo is finally gonna go against an espada .
