Re: unresolved plot lines
I have another one that really bugs me. Aizen captured Orihime and said he'd need to use his powers, and I guess he did to a certain extent-healing the espadas mostly. And I know he said his real intention was to lure out Ichigo and everyone from SS. Seriously, though, Kubo's made Aizen out to be too much of the evil mastermind type for him to NOT use Orihime's powers for a significant purpose. And there are two manga reasons that back this up:
1) Orihime never really does much, and is always talking about how she needs to be more useful, meaning she wants to help. Which leads to
2) Aizen didn't have to show her the Hougyaku to get her to trust them, because they had her locked up in a room anyway. That makes me think he WANTS Orihime to use her powers on it, probably to restore it to the point where it was most active.
