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.
Jerkass Woobie - Jake himself, at least by the end of the first book. His friends betray and/or ditch him and his family is brainwashed by the heroes so that they don't remember, and in fact can't even see him. Even if he brought it on himself, that's still pretty harsh.
