"Very well," Sister Merope Morfin frowned. "And as further punishment, you will fully bathe the soiled Mudblood. Scrub her filthy genitals with as rough a cloth as you can find, to remind her that our fine linen is not to be begrimed by her dirty urine. Go, do it now ... and I expect you to drill the message in loud and clear, Sister. I will check in the morning that you have done this, and I expect the skin to still be raw. If it is not, we shall add that punishment to the list to be handed out to you."
