Charlotte Anne Jane is the child of Angela Ruskin Jane and Patrick Jane. Both she and her mother were murdered by Red John and it is her father's sole purpose to exact his revenge on her murderer. Before her murder Charlotte showed signs of being a talented pianist. When questioned on her death in the season finale of season three it is quoted by Red John that Charlotte "smelt of strawberries and cream" before he murdered her. Charlotte is portrayed by Isabella Acres and Dove Cameron (Charlotte Anne Jane as a teenager in season 5 because of Patrick Jane's hallucinations).
Charlotte's three names, Charlotte, Anne and Jane, all have something to do with the Bronte sisters. Charlotte's the name of the oldest sister, Anne was the youngest sister, and Jane the first name of Charlotte's most famous protagonist, Jane Eyre. The name might also allude to the word "charlatan," given her father's profession while she was still alive.
In Jane's hallucinations the teenage Charlotte appeared to have mentalist skills comparable to her father.
