In later seasons, Sabrina was enrolled at the fictional Adams College in Boston. Sabrina also at some points transforms herself into Libby to gain popularity (Libby is the queen of the school) for her "dorky" activities. She also had to deal with the snobby and headstrong cheerleader Libby Chessler, who became Sabrina's rival for school activities as well as Harvey's affections. They get back together later in Season 4 and then break up again when Harvey discovers she's a witch. In season 4, Harvey believes Sabrina is cheating on him. In the finale they finally stop dating due to Salem driving a car into him. She also has to deal with her Vice Principal Kraft who dates her aunt Zelda and then in season 4 becomes principal and stops dating Zelda and then goes back on and again not due to car crashes. At Westbridge High, she befriended Jenny Kelley (and later Valerie Birkhead in seasons 2 and 3) and had an on-again, off-again relationship with Harvey Kinkle. She also learned that her two aunts were witches themselves and that their black cat Salem was a witch who had been turned into a talking household pet as a punishment for attempting worldwide domination.
On her sixteenth birthday, she learned that she was a half-witch (through her father's side) and had magical powers. Sabrina is depicted from the middle of high school through all the way to marriage.
