Chelsea felt like the black sheep of the family. She couldn't pass the academic criteria to go to Oxford like sister Libby, but she had more brains than people gave her credit for. Though on the surface she was vain, indulged, and argumentative, this was a cover - she wasn't as tough as she made out. However, Lucas was a murderer, accidentally killing his ex Trina and deliberately killing Denise's ex Owen - he then held Denise hostage and faked her death. When Denise escaped and Lucas was convicted, Chelsea struggled to live a normal life.
