On an evening in early March 1989, Gersten welcomed her family, Leland and Sarah Palmer, and Maddy Ferguson to the "Hayward Supper Club." She wore her fairy princess outfit for the school play and said she had received the highest grades in math and English, like her sisters. Gersten presented Harriet, who read the Palmers a poem about their deceased daughter Laura as Gersten played a piece on the piano. After the poem, she played Mendelssohn's "Rondo Capriccioso, Opus 14."
Gersten took college-level courses in high school, graduating at the age of sixteen, and was fluent in four languages. She entered Stanford University, but suffered a nervous breakdown during her second semester.
She was treated at a Bay Area psychiatric hospital and returned to Twin Peaks. Although her health improved, she soon became dependent on opioids and designer drugs. Following her mother's death in 2009, Gersten began a series of reckless and chaotic relationships with several individuals, most notably with Steven Burnett. Their off-again, on-again affair preceded and overlapped Steven's marriage to Becky Burnett. In the interim, Steven had become Gersten's primary source for narcotics.
On a day in late 2016, Steven's wife, Becky, showed up at Gersten's apartment in a rage and shot through her door, believing them to be inside, while Gersten and Steven listened from a nearby stairwell.
Later, Gersten and Steven, seemingly under the influence, went to the woods behind Steven's trailer park, where they sat against a tree. Steven held a gun and rubbed his leg, distraught over something he had done. Gersten tried to console him and talk him out of suicide, insisting that it was "her" fault and that he had been stoned. They were interrupted when Cyril Pons approached them, walking his dog. Gersten jumped up and ran around the tree, while Pons turned and fled. She listened in horror as Steven fired his gun.
