On the eve of Phineas Holstrom's eighteenth birthday, she and him are driving along a country road listening to music as Phineas explains how math is in everything. When she offers to get physical, Phineas stops at a gas station for beer and condoms. She waits in the car and is killed when a truck speeds into the car.
Years later, her name and appearance was adopted by Rachel Brooks in an attempt to give Phineas's clone, Caspian Keyes, similar life experience so that the clone could cure the flaw.
