Abigail Chavez first appears in Seeds of Discovery as Quinn's best friend from childhood, although it is clear from the beginning that the two of them are growing apart. She is much more interested in dating and boys than Quinn seems to be, and in Seeds, she begins dating Adam Lamos. In Roots of Insight, she attends the Valentine Dance with him. Abigail is a junior at Bristlecone High School.

Abigail's older brother, Louis Chavez, is a Bristlecone police officer.
