Born Olivia Svenson, Olivia becomes Angier's lover while he is on tour in America. He takes her on as a lover and as an assistant, bringing her back to London with him, where he leaves his wife for her. She changes her name to Olive Wescombe and arrives in Alfred Borden's life while applying for the position of his assistant. She and Alfred become lovers as well as a stage team, but Olive reveals that she was originally sent to Borden at the request of Rupert Angier to spy on him, but in truth, it was Olivia's idea to seek out employment with Borden. For this reason, she requests that she no longer maintain the place as his assistant so as not to provide Angier with any expectations that she will have access to his work. Instead, Borden has her play the part of a double agent and provide Angier with false or half information, taking to Angier the name of "Tesla" as the secret to his illusion. Olive later witnesses the death of Alfred Borden and then discovers he is again performing on the stage. She is convinced Borden has left her and seeks to sell his journal to Angier for the funds she needs to remain in her home.
