Re: unresolved plot lines
also the situation with kurosaki isshin has been bothering me.
i recently watcehd an old episode where isshin kills the grand fisher and uruhara says "how does it feel to be a shinigami again after 20 years". this means he would have been captain only 20 years ago so surely someone from SS should know him. it also means that aizen knows him and he should have somehow figured out ichigo was his son from the first moment he fought him.
isshin also says that they contacted ichigo "like they said theywould". this means that he either saw one of them or they somehow communicated a message to him.
lastly he tells urahara that the vaizards are preparing for a battle "just like we are" so im assuming that they would somehow get involved in the fight
