Born with acute autism, Bethany had problems relating to other people and disliked noise and physical contact, often reacting violently to changes and disruptions in her life. She also tended to be very quiet. She was, however, a very talented artist even from a young age. Her mother kept her at a secret clinic in San Diego in the care of Doctor Gerard, in order to prevent her from becoming the subject of media attention. She also lied to her abusive husband Boz Skannet, Bethany's father, and told him that she was dead to prevent him from finding her.
Bethany and Cross
As Athena's relationship with Cross De Lena deepened, she eventually took him to meet Bethany. Bethany took a liking to Cross and the two eventually developed a strong bond. Bethany went with her mother and Cross to Paris in 1997, moving back the following year with her nanny Josie Cirolia after Athena was killed with a bomb meant for Cross. The three of them began to bond, at one point buying on a dog on a shopping trip that was disturbed by a drive by that resulted in the death of Cross's bodyguard and driver.
Unbeknownst to Cross, Cirolia was actually an FBI agent, and she would have continued to spy on him unimpeded had Bethany not accidentally revealed her recording device to Cross, which eventually resulted in Josie's murder. Afterwards, Cross presumably got a new caretaker for his stepdaughter, though Bethany had clearly developed a deep affection for Josie and mourned her departure.
