Sheriff Stilinski

The Sheriff's name is John.

Malia Tate

The fanon surrounding Malia is the source of a lot of hate toward Malia's character and wank in fandom in general. Malia was in her coyote form for 8 years. Fans, rightly, assumed that this meant that she would be developmentally stunted--a mental 9-year-old once she turned human again.

However, canon has clearly shown that this is not the case. She is presented as a fully functioning teenager, with an advanced vocabulary and mature understanding of the world. Whether or not this is sensible or realistic, it is canon. Objections to her character or her character's capabilities that base themselves on the "mental age" she "should" be are based on entirely on fanon and on assumptions built up within fandom after her initial introduction but before anything more about her was elaborated upon.
