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.
Miles thinks that Delgon might be one in-RP, due to his constant grinning and smiling which makes the tanker uncomfortable. Made moreso unfortunately implicated that Delgon replied that he does have a darker side, and then proceeds to laugh "half-mad" and chuckle evilly.
Sympathetic Sue: Kacie (Katie's sister). She witnessed her parents' deaths? Abusive foster parents (whom her bio states she's beaten by every nine hours)? Racism? Self-pity and thinks she deserves all of said punishment? Practically screaming and sobbing towards anyone who tries to help her, for fear of more abuse like that of her parents? If that doesn't qualify for a Sympathy Sue, then it very much so touches the border on it.
Kacie also constantly talks about her tragic past to people who she's barely met, which is very unrealistic when compared to actual victims of abuse.
