User blog comment:Caesarea37/Aizen and the current state of his Zanpakutō/@comment-1393830-20130319190356

I think it is fairly simple to explain. He lost track of time. Ever lost track of time talking to someone? Think you've only been talking to someone for a few minutes but actually been talking to them for a half hour or more? Aizen likes to talk and is a master at manipulating people, he likely did this on purpose.
