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.

Moral Event Horizon: The author has stated that the Queen's murder of Count Bleck was supposed to symbolize the point where she crossed this line, at least in the present day. (Andy's angry reaction to it was supposed to express it as such.)
