This really blows my mind.

Why didn't Ichigo's dad kill Grand Fisher at any time before this, especially during "Memories In The Rain"? And why did he let his family get torn up by that shitty hollow at the beginning of the story?

There's no way he is just bullshitting unless he somehow knows what a Shinigami captain uniform looks like, AND that his son's body is being possessed by Kon.

This twist really threw me for a curve
