Lucy Sell is a character who can be seen throughout videos in the Violette1st YouTube video collection. She is the Sister of William and Kelsey, the daughter of Bill and Violette, cousin to Andy, and the adoptive mother of Zachary.

This act is an exemplary example of how Lucy deliberately starts issues involving William. Even from the earlier videos such as William And Lucy Fight Over Wii Video Game System, Lucy, and William appear to have signs of sibling rivalry as they fight for the Wii game console. During this video Lucy says that he is
