I just had a new thought. Aizen wants Orihime to restore the Hogyoku to its non-cracked state. As Orihime's power is basically time reversal, if the orb is restored to a non-cracked form, several months or so of awakening are going to be deleted, for lack of a better term. If this happened, the Winter War will actually be much further away than we thought. However, Orihime has resolved to erase the Hogyoku completely. So what if Aizen's plan is to let her bring it back to the moment of its creation before stopping her? The orb was "put to sleep" by Urahara (i think) so if this was the case it would be ready immediately as it would be awakened completely, and the war could be far sooner than we thought. Any ideas?
