The mother of Ensign Harry Kim, who talks to her son from Earth in Author, Author and wants to know why Captain Janeway has not yet promoted him.
Mary Kim appears in the Voyager episode Author, Author, alongside her husband John. Harry often mentions her, and the clarinet she encouraged him to play, as part of the life he left behind when Voyager was lost.
In 2377 the Pathfinder project makes brief real-time conversations with Earth possible, and Harry uses his turn to call his parents. Mary is overjoyed to see him and immediately begins to mother him across thirty thousand light-years.
She is puzzled that he remains an ensign and suggests she might write to his captain about it, to Harry's dismay. The scene plays lightly on the series' long-running joke about his lack of promotion.
