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.
The Scrappy: Briony. Although it doesn't really get bad until the fourth book when all her character development and learning about how things are not necessarily how they seem goes out the window. From this point, her sections of the story become a real trudge through her accusing people of things without having all the information, making extremely unreasonable demands and whining when she doesn't get her way. Arguably justified in-story since she has just got back to Southmarch, Midsummer is approaching and everybody with the god's blood is acting strangely, and she does get her requisite CMOA towards the end.
