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.
YMMV: Children of the Red King
Complete Monster: Yolanda. She not only murders Paton's mother by tossing her down a flight of stairs, she also corrupts his sisters into what they are in the series.
Yorath counts as this as well.
The Untwist: Seriously, is there anyone who didn't guess that Mr. Pilgrim was Charlie's father?
The Woobie: Billy Raven has this hard. Each book introduces some new torment that the poor kid has to go through.
