...Grimmjow had both arms in the post-episode "Encyclopedia of Arrancar" bit... An oversight, perhaps? Would seem so, given what Ulquiorra said last episode...
Rehashed stuff we already know, subpar animation, characters doing their normal "this is what makes me unique" bits from previous episodes, brand new story that pales in comparison with what it's interupting, and the knowledge that more is on the way next week...
I am currently trying to forget that this episode even happened.
