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.
Fridge Brilliance: Davis has a pretty good knack for foreshadowing. For example, one or two throw away comments from the first book on Billy's drawing style being similar to somebody else's were forgotten by the majority of fans until it was revealed that the other artist is Billy's grandfather. Six or seven books later.
