I know some of this is the whole 'lol six am' thing talking, but I am so tempted to write like. A long essay on the Zanpakuto Rebellion arc and what it tells us about different characters. Despite the fact that the plot was kind of awful and contradicts the rest of canon horribly, because hello, how do three of the oldest shinigami captains (two thousand years plus old) not know about a major uprising and exile of a Kuchiki. Even if the records were sealed. And let's be honest, the Beast Swords arc was pretty much pure, unadulterated crack. Delicious crack, but crack nonetheless.
But I love love love the zanpakuto spirits and their personalities. And the ones who aren't just like their masters (as opposed to say, Zabimaru or Hyourinmaru or Haineko) tell us a lot about their wielders. Senbonzakura is actually highlighted in that regard, that his impatient, short-tempered nature is actually an innate part of Byakuya, just one he's gotten better at controlling. And honestly, I could dedicate paragraph after paragraph about what Sougyo no Kotowari (who are actually responsible for me thinking this - I was discussing how I play them in BDR with someone) says about Ukitake's inner wants, or what Katen Kyokotsu tells us about Kyouraku, or how Tobiume confirms my guess that Momo is secretly awesome inside (well, okay, she's still pretty awesome outside too). And I kind of wish we had seen more than like thirty seconds of Minazuki, because I have realized in the last week or two that Unohana is probably my second-favorite captain after Ukitake. I blame Retsu and Jyuushiko's budding friendship, which is absolutely adorable, and I crave more of it.
However, the fact that it is stupid o'clock in the morning means that no, it's not actually going to get written. Not write now, anyway.
