"I can not speak well enough to be unintelligible."
- Ascended Fangirl
- Black and White Morality: Catherine's firm belief at the opening of the novel.
- Break the Cutie: Catherine gets this treatment when she is pretty much thrown out of Northanger Abbey.
- Cloud Cuckoo Lander: Catherine has a rather...er... 'odd' interpretation of the nuances of society - or rather an incredibly naive and innocent one: she doesn't think that anyone is capable of outright lying and manipulating other people and situations and could never do such a thing herself. To make matters worse, half the time her mind is with her Gothic Novels and a little departed from reality - with an unhealthy slab of Wrong Genre Savvy. In spite of this, or maybe because of it, she comes up with a lot of Armor-Piercing Questions that she'll ask A) without realising that they are in fact armor-piercing, and B) without realising that the questionee is extremely uncomfortable. She ends up feeling very confused when the person she's talking to suddenly changes the subject.
- Country Mouse: She came from a rural home where everyone was rational and straightfoward. She becomes very confused by the hypocritical and egotistical behaviour she meets with in Bath.
- Genre Savvy: But she knows quite a lot about the world of Gothic literature.
- I Didnt Mean to Turn You On: To John Thorpe
- The Ingenue
- Love Triangle
- Na´ve Everygirl
- Na´ve Newcomer: She is completely inexperienced with the world at large and the social life in the cities. This doesn't exactly pan out well for her.
- Outdoorsy Gal: As a little girl, Catherine hated confinement and cleanliness, and loved rolling down the green slope at the back of the house. She liked playing cricket, baseball, riding on horseback, and running about the country. When she's grown-up, she still loves taking long walks and spending time outdoors and breathing fresh air.
- Selective Obliviousness: Good grief. She's a fangirl of gothic novels and imagines things accordingly. But she misses the fact that her best friend, Eleanor, is the living embodiment of the stereotypical gothic heroine — estranged lover, dead mother, overbearing father, lives in an abbey with said father and the creatures of the forest, always wears white. Well, she notices but falsely assumes SHE'S the heroine (and is correct, just for the wrong book).
- Single Woman Seeks Good Man
- Blue Blood: In the end.
- Lonely Rich Kid: She spends a lot of time in the abbey alone or in the pleasant company of the General. Henry even thanks Catherine for coming to stay, considering it a real favor to Eleanor, while Catherine is thrilled with the invitation and thinks she's the one who ought to feel grateful.
- Nice Gal
- Sacred Hospitality
