Of course I owe you. This curse has been upon me since I arose and descended for breakfast this very morning... To my great shock and despair my breakfast, while ordinarily quite delicious, tasted most unpleasant. Beyond the flavor of merely spoiled food, it was instead the taste of ash-!

Such has been the case with everything I've eaten today.

[Woe is Yusuke, etc. He raises the remaining half of the chocolate bar.]

Your offering, for the record, tastes distinctly of soap. I am able to stomach it, but at severe cost to my psychological wellbeing...
