Steffy is named after her paternal grandmother Stephanie Forrester (Susan Flannery), with Wood affirming: "She's always thinking. There's a reason she was named for her grandmother, Stephanie. There's always a tactic, always a strategy." Steffy and her brother Thomas have always dreamed of their parents Ridge (Ronn Moss) and Taylor (Hunter Tylo) reuniting. In 2009, the siblings manipulate their parents to get them back together in marriage. The storyline, inspired by "The Parent Trap" (1961), sees Steffy and Thomas tamper with SMS text messages between Ridge and his former love, Brooke Logan (Katherine Kelly Lang) to make Brooke believe that Ridge had dumped her, so she will not interrupt his reunion with Taylor. However, Brooke crashes the wedding after the marriage becomes official.
