These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Harsher in Hindsight: Queen Ozma's portrait hangs in Petra office and is used as a dart board. It is even made into a little Running Gag - for example, when Petra later sees the portrait at Riggedo's bar, she asks him if he minds playing a little game of dart. After The Reveal, it becomes painfully clear that Petra has more reasons to hate Ozma that she may think.
