Emily is well versed in French language and culture, under the care of Renee and Marie Helene. Her mother is a gold digger and has no devoted father figure in her life. Basically the same as Eloise Thompson. She can be surprisingly impolite at times, while a loyal friend at other times. Because of her mother's social status, Emily gets to attend parties that D.W. never got invited to. Despite this, Emily apologized to D.W. which helps since D.W.'s parents, who party quite often, were very apathetic towards D.W.'s misery. Her hair was inexplicably short in the first five seasons until it grew longer to be more consistent with the books. Emily and D.W. are there whenever The Tibble Twins need supportive friends.
