After much speculation, "Days of Our Lives" fans finally learned the reason behind Chanel DuPree and Sloan Petersen's heated feud. During an emotional episode, Chanel opened up to Allie Horton about her connection to Sloan, revealing that while in college in London, she had a torrid affair with Dr. Nathan Bedford, one of her professors and Sloan's father. Eventually, word of their affair got to his wife, Sloan's mother Martha Bedford, who texted Chanel and asked her to meet up on the roof of the university. When the two came face to face, Martha was angry and the two began to argue. Eventually, things got physical when Martha lunged, causing Chanel to push her away. However, Chanel didn't realize how close they were to the edge of the roof, and Martha fell to her death.

After the police arrived at the scene, Chanel's mother, Paulina Price, offered a large monetary donation to the university to keep the incident under wraps. The school then claimed that Martha had committed suicide. Of course, Sloan knew differently and set out to make Chanel pay for what she had done to destroy her family. So, she began blackmailing Chanel and Paulina, though the police ultimately got involved and worked to dissolve the issue.

However, Sloan hasn't forgiven nor forgotten Chanel's part in her mother's death.
