Things I'd like to know linked to this are a) how did these Souls learn how to control their spiritual power, and b) how/when was the Gotei 13 founded. We know comparitively little about the history of Soul Society and the Gotei 13, beyond knowing some dates. Maybe if Yamamoto survives he can answer those questions (I'd like to learn more about his role before G13, when he was younger).
