Under the DomeEdit
Laura is only mentioned briefly, when Melanie Cross tells Barbie about how her mother was in a hurry to get out of Don Barbara's house. After Melanie mentions her name, Barbie quickly realizes that his parents used to argue about a person named Laura, due to Don having a kid with her while still being married. Barbie then says that they are half siblings.
