When Blair’s mother, Rachel, passed away from cancer, she was not only grieving but also feeling betrayed. Blair, 25, had always been close to her mother, while her father, Greg, distanced himself during Rachel’s battle with stage 4 cancer. One night, Blair caught Greg at a romantic dinner with Lisa, Rachel’s coworker. Heartbroken, she confronted him, but kept the truth from her mother, who made Blair promise to hold him accountable.

After Rachel’s death, Blair discovered her mother’s journal, which gave her the blessing to heal however she needed. She inherited half the house and secretly planned her revenge. Blair pretended to support Greg and Lisa, only to later serve them legal papers, selling her half and evicting them. When they announced their engagement, Blair sent Jenna, their wedding photographer, photos of their affair. At the wedding, Jenna read the letter aloud. Lisa fled, and Greg was left stunned. Blair kept her promise.
