Years after Vivian Alamain's marriage with Victor Kiriakis had ended, she still found herself in love with her former partner. Victor had long divorced Kate Roberts and had moved on to have feelings for Maggie Horton (Suzanne Rogers). Of course, Vivian became wildly jealous of Victor and Maggie's relationship and concocted a plan to eliminate Maggie from Victor's life (via Soaps). Vivian recycled one of her most devilish plots and decided to have Maggie buried alive. However, Brady Black (Eric Martsolf) found out and saved Maggie while also getting his own revenge on Vivian by placing her in a sarcophagus, per Soaps in Depth. Vivian later left Salem, but would return with a shocking bombshell.

In 2018, Vivian made a splash when she showed up at a New Year's Eve party with a handsome man on her arm. Vivian revealed that the man was actually her long-lost son, who was fathered by none other than Salem's most notorious villain, Stefano DiMera (Joseph Mascolo). The man revealed that his name was Stefan O. DiMera and that he planned to claim his part of the DiMera fortune, business, and legacy (via Soaps in Depth).
