Big Lipped Alligator Moment: The story doesn't have much of a plot to begin with, but most notably is a moment shortly after Danisha almost gets molested by Frollo; Danisha tosses a quarter at him and tells him to "call somebody who cares" for no readily explained reason.
Danisha thinks Christopher Columbus was Spanish (he was Italian) and that America was a country during the 1480s (it wasn't and hadn't been discovered yet). The worst part is that both she and her real life counterpart are Social Studies teachers.
The FanFiction Critic: Ladies and gentlemen, this is why children today are stupid; because idiots like this author are allowed to teach.
Additionally, Danisha goes around her first visit to Medieval Paris managing to wear an outfit that shows off her legs and everyone runs to her and wants to talk to her. Except that in Medieval Paris a woman wearing a fancy but revealing outfit would likely be mistaken for a prostitute.
The fact that glass windows were not available to the peasants, and the glass windows that existed were not transparent.
Danisha occasionally speaking in 'old negro dialect', and everyone understanding her as if it would translate fluently into French.
Adding to that, during the party that Danisha throws later in the story, she and her friends decide to get up on stage, and sing a bunch of Motown songs. One can only imagine what that sounds like in French.
Also during the party, Danisha, and company cook up a bunch of food that Medieval Parisians would have never seen before, and yet they expect them to all eat, and love it. Additionally, the food served probably contains chemicals, and additives that would most likely end up getting all the Parisians sick.
Danisha herself is this as well. We're supposed to believe that she's loving, pure and good, but she shows the same amount of racism Frollo does, vilifies Esmeralda and punches her in the face because she refused Frollo's advances, and completely condones Cold-Blooded Torture. There's also the rather infuriating fact that she only cares about people she actually knows: someone she knows personally is wounded? She's all concern and tears. Someone she doesn't know personally is bleeding to death slowly and painfully when they don't even deserve it? She laughs at them!
Designated Villain: Malus and Esmeralda. Malus actually does do something bad (it's never specified), but Esmeralda is only the villain because the author tells us she is.
Fan Wank: The author has her own convoluted theory about "what really happened" during the events of The Hunchback of Notre Dame. After the Festival of Fools, Frollo is kidnapped by Clopin and replaced with an evil Frollo look-a-like who proceeds to wreak havoc on the city for the sole purpose of making the real Frollo look bad. Luckily, the real Frollo was rescued and the impostor fell to his death.
Fridge Brilliance: When you think about it, Danisha's personality actually does make her perfect for the Disney version of Frollo...in an Unholy Matrimony way rather than a cute way. They both hate Gypsies, they both blame others for their own awful deeds, both treat Quasimodo like dirt and they both want Esmeralda dead.
Ho Yay: In one of the follow-up stories "Did It Blow Your Mind, Claude Frollo?", it almost seemed like Iggy (another one of the author's characters) was going to develop a romance with Claude's brother, Jehan given how much the narrative pointed out how similar the two of them were, only for Iggy to end up with his ex-girlfriend via extreme contrivance.
Les Yay: Danisha seems to be very close to her friend Fern and rarely has a bad thing to say about her. The two of them seem to naturally get along in a more healthy way than Danisha and Frollo do, so much so that one almost has to wonder why these two aren't in a relationship together instead. (Of course Danisha's only been with men and Fern's married, but there are ways around that.)
Moral Event Horizon: Frollo Freak wants us to think the Gypsies kidnapping Frollo and trying to mess up his good name is this. The real Moral Event Horizon is Danisha leading a group of people to burn down the Court of Miracles and gun down the Gypsies for it all, effectively attempting a genocide.
