Pretty awesome episode. I like how Ichigo didn't waste too much time using the Final attack. He already waited too long as it was since Aizen's power up had already been enough to withstand Ichigo's final attack, but luckily Urahara sealed Aizen away. I'm actually pleasantly surprised Ichigo didn't wait longer. It goes against a convention of waiting until you need Bankai to actually activate it. We saw it with the Espadas for example. And Ichigo actually said it up front that he needed to end this quick.

I agree it's a nice point to end it. Still, I'm curious about that talk about the Spirit King.
