I just feel like most people need to take a chill pill no matter if it's rl or fandom

But if everyone was calm and rational, imagine how boring the world would be! ;) But yes, I definitely agree with this: Why would you ever use a normal person in storytelling? Becky is over-the-top because she's used as a source of humour -- portraying fans "accurately" would be, as you say, boring. Also, if they were going for accuracy, there needs to be a whole lot more girls at the convention -- guys cosplaying as Sam and Dean? How unrealistic! X3
