Don't underestimate the tendency for a society raised to be a monarchy to continue to function as a monarchy. Tradition holds a strong place in people's hearts, and frankly the worthiness of a monarch rarely determines how well their subjects treat them. The situation they're in is currently working, given the circumstances, even if it's the subordinates carrying the weight of governance, so it's unlikely the average person in Io has a problem with Fatty McInfernoReference.
And yeah, Miss Hottie Aide is totally rocking some elf ears under that hair.
Of course, I'm starting to think our own side's badass hottie whose hair conveniently always covers her ears isn't human either...
