On May 18, 2020, around three months after Wiley's true identity was revealed and Brad was arrested, Nelle blackmailed Julian into marrying her with the information that he caused Lucas and Brad's accident and kept Wiley's true identity a secret. She revealed Julian as her new husband during her custody case for Wiley.
On August 12, Nelle was shocked when the judge awarded Michael full custody and gave her zero rights to visitation.
On August 20, Julian kidnapped Wiley from the Quartermaine Mansion and chloroformed Monica Quartermaine in the process, all because he was forced to do so by Nelle. However, after bringing Wiley to the pier, Julian tried to kill Nelle, but the presumed dead Marcus Taggert arrived and saved her at the cost being shot in the shoulder by Julian during a struggle. Nelle took off with Wiley for herself, but they were found by Michael (since Julian put Nelle's tracking device in her car).
On August 27, Nelle died after falling off a cliff while trying to escape from Carly.
