To demonstrate.
Iothael: … You must thank our mother for me. It is taking from the recesses of the very depths of my patience not to just throw you out, Basal. You live in a world of privilege, you eat and drink, you are not in danger from harm or an untimely death, you have everything within your reach, as I have allowed for you and the rest of my... family. And yet you spit on my generosity, you make yourself the enemy to anything I say, do, or touch. But just as our mother neglected to make me a waif on your whim, I will return the favor considering mine.
Basal: Look at you, all high-and-mighty, justifying my imprisonment and slavery to you so eloquently.I'm sorry, dear sister, that it is so difficult for you to allow me to live. I'm so thankful.
Iothael: (growls) Let it be known that your death has never been completely out of the question.
