Guybrush finds a leaflet of her posing cosily with the judge and he originally thinks she is his wife—however, the judge states his wife has red hair whereas Elayne is blonde. When Guybrush asks Elayne about it, she becomes very defensive when she insists it isn't her in the picture. Guybrush later uses the pamphlet to blackmail the judge into giving him a fair competition against Marco de Pollo.
