What struck me as interesting about that whole scenario was how utterly useless and ineffectual Hazel and Gato were, bearing in mind they haven't hesitated in the slightest to stick their noses in Sanzo's business in the past.

We got to see how much of a mindfuck he did on Kamisama and chibi-Hazel, it looks like it went a lot further with Hazel than I had believed. Ukoku believes in making a lasting impression, I guess. I wonder if this is how he is starting the same process with Sanzo.
