Very little is known about her, other than that she, according to THE MARRISSA GAMES, died and/or was heavily injured in a car crash due to not fastening her seatbelts, seemingly after TEEN FORTRESS 2 was written but before THE MARRISSA GAMES was written.
Marissa, being that the two are good friends, inserted her into TEEN FORTRESS 2. This fictional version is only mentioned once, as Scot's former girlfriend. Unfortunately, Scot's brothers killed her and defaced her corpse. Later, when Scot and Snipper found an escaped zoo koala, they decided to name it Katty after this friend.
- She is the only person involved with MarissaTheWriter stories whose death during/after the stories were written is suggested.
- Katty was inspired by Raven, Tara Gilesbie's friend who edited My Immortal and had her own self-insert, Willow. However, during the course of My Immortal, Tara and Raven broke up, and therefore the quality of the writing decreased and Willow was inexplicably killed off. Despite this, Katty never directly interacts with Marrissa's text; in that respect, Logic Editor fits Raven's role better.
