Slightly Damned/Headscratchers

• On the second page, Death explains that Rhea's destination is unknown, and that he has to figure it out manually. However, on the fourth page they already have an appointment (with Buwaro) in the Ring of the Slightly Damned that they are in danger of being late for. Note that vanishingly few souls go there, so Death couldn't possibly have just guessed.
  • Death dropped in to see Buwaro in hell every other day while they were down there. He was probably doing that well before Rhea showed up.
• Angels have their own language, which is a plot point several times in the form of a language barrier. So why do demons all speak Lingo like Medians, instead of speaking Black Speech?
  • Its to be assumed that Demons have more interaction with Medians than Angels do, as the demons have the role of torturing the sinful ones, while the Angels have no obligation to interact with Medians at all.
• Why does Buwaro stomp on Rheas tail? He seems actually evil for a second, then turns back to a lovable moron. What happened?
  • He was just trying to immitate the other demons, after he got friendly with her, he probably just forgot that he's suppose to torture Rhea as an advisor.
