Before Season 1Edit
Mark and David Aceveda studied together at the University of Southern California. During Aceveda's relationship with Maureen Wilmore, Mark and Peter overheard Aceveda talking about how she was a masochist and that she liked to "play rough" during sex.
When Aceveda broke up with Maureen, Mark and Peter went to her room and tied her up. They then raped her. She never told David about what happened, but instead presented charges against him for the rape.
Fifteen years after the incident, a reporter interviewed Maureen Wilmore with the purpose of releasing a damaging article about David Aceveda. Knowing that he had never raped her, David visited Maureen to convince her to tell the truth. However, Maureen broke up and confessed to David that Mark and Peter had raped her.
