Lionel Harding was obsessed with the Mona Lisa and did not show any interest in his dedicated assistant, Phyllis Trupp. When the Mona Lisa came to life in 2009, he followed her and tried to help her until he had enough and realised she was not what he had imagined her to be.
To stop her, he destroyed the Chinese Puzzle Box, her last hope to free her brother and leave the gallery. He was shocked when the Mona Lisa said she did not want to experience the world, but to destroy it. Once the Mona Lisa was returned to her rightful place in the painting, he found new appreciation for Trupp and tried to express his affection for her. She, however, did not forget how he had treated her when Mona Lisa was alive and rejected him. (TV: Mona Lisa's Revenge)
