orihimes healing abilty doesn't actually heal in the normal sense of the word, orihimes abilty is to restore whatevers within the barriar to a previous state. it more like a time reversal tecnique that affects anything within the barrior.
so restoring grmjows arm is entirly within her ability.

good episode, but i really feel like smashing my comp screen every time precious minutes are wasted on flashbacks, 5-10mins of flashbacks is alot in a 30min episode, it doesn't help that the flashbacks are just from the previous weeks episode. my memories not quite that short.
strange no preview of next episode, hmmm......
