Maggie Sibley is the only daughter of George Sibley. She becomes close friends with Nate Fisher after she moves to LA to care for her ailing father. Nate confides in her his worries about his and Brenda's unborn child who may be born with special needs. Maggie understands this since she had a child who died from leukemia when he was two.

Nate ends up committing adultery with Maggie on the evening of his seizure and a guilty Maggie attempts to make amends with Brenda, to no avail. Maggie leaves town following Nate's funeral and an argument with her father but Ruth phones her to ask if Nate had been happy prior to his death.
