Actually Minato88 I must disagree with you in terms of Orihime. She COULDN'T revive Tsubaki before because she BELIEVED she needed a piece of him. However, Hachi showed her that, that wasn't the case and gave her some info on her power, the famous (or is that just me) line about "it doesn't matter how things are but more how you want them to be". Aizen again gave her a better understanding of her powers. Not saying she can being back Ulquoirra but I doubt she'll ever have issues reviving Tsubaki or anyone like that ever again.
