Affably Evil : Kimberly tries to write an article about Brandi's trial, and, seemingly, to befriend her, and could be seen during the whole movie as a naive, yet dangerously zealot and shallow bigot. Whether she is this or manipulative remains unsure...
All Take And NO Give : Brandi and her brother, for most of the movie. Brandi and her father, initially.
Amoral Attorney : Manipulate testifyers ? Check. Work for the villains in a witch trial, yet mentions his son, Faux Affably Evil ? Check. Turns testimonies to his advantage with very bad arguments and no real point ? Check.
Easily Forgiven : Casey dumps Brandi. Casey participates in spreading rumors about Brandi being a witch. Brandi gets expelled. Brandi comes back. Casey gets dumped by her new friends and accused of being violent. Brandi makes her remark that their situations and behaviors were Not So Different, and Casey (mitigating this trope) sincerely apologizes. They get on well after that, and Casey becomes a much better (notably more supportive) friend.
Hidden Depths: Everyone, but mostly Brandi ! Who could believe that she would been so accepting and forgiving towards her best friend and Kyle.
Honor Before Reason : Brandi's mom, who could get well-needed money by asking for a dedomagement, but prefers suing the high school...
I Just Want to Have Friends : This is a deconstruction. But instead of being about how a protagonist is doing anything to get the approval of a bad teenager and her Girl Posse and accidentally hurts her friend , it is about the best friend of a protagoist and she (only a little but deliberately) turns on her, the keypoint of the deconstruction being that she cares for the number of friends and their popularit y, but initially not for the quality of the friendship. But she is a very lovable character and is shown as behaving like most people expect her to, and it is clear that the realisator refuses that we blame her in the end, so the blame and the deconstruction are more about the expectation she lives up to than about her personality.
Innocent Bigot : Perhaps Kimberly, as far as "innocent" could go with her. "Naively self-serving without getting the consequences". Perhaps...
Light Is Not Good : All the christian fundamentalists and manifestants, Kimberly, the principal, the attorney. They dress, speak and act with a light, non-threatening, yet always distinctly creepy/annoying quality about them.
Oh, Crap : Brandi's (and the viewer's) reaction when the assistant asks her if she thinks of God when she practizes sorcery, prompting a realization that this is going to be a witch hunt.
"The Reason You Suck" Speech : Brandi gives one to her friend Kyle. She calls him out on his careless behaviour, and tells him that him seeing everything as "fun" is nice in his own life, but not in hers. However, it is recognized as unfair from her, as he is basically the most honest and spontaeous friend frequenting her.
The Snark Knight : Brandi and Kyle are initially played like this. He is sure to lampshade the "only independant minds Surrounded by Idiots" part and analyzes why he thinks it is the case when he incrimines the other student's lack of knowledge of the world outside what they learn in school and in the church. Brandi criticizes his view by demonstrating his superiority is mostly coming from his inability to take his life seriously.
