Rebecca Goth is a non-playable Sim shipped with the game in Sugar Maple Coast, a neighborhood in The Sims 3 Pets (console). She lives with her cat, Buttons Goth. Her relationship, if any, to the Goth family is unknown.
Rebecca was drawn to Sugar Maple Coast due to the stories of her family there. Her great-grandfather is said to have carved the town out of the wilderness implying she is probably a descendant of Timaeus Goth, one of one of the founders of the town. He and Angela Gilman are buried at the Goth Family Cemetery. Angela was married to a Goth but never changed her name. It is likely that she is either Timaeus' wife and therefore Rebecca's great-grandmother or possibly Rebecca's mother. The Goth family left the town shortly after Angela's death but now Rebecca is back and trying to find out more about the many mysteries surrounding her family's history.
Rebecca can be made playable by asking her to move in or marrying her, though she is Unflirty so marrying her may be difficult. She has no friends other than Buttons Goth due to her Loner trait. Rebecca is also a Bookworm with three writing skill points and wants to become a Professional Author, but since she is employed in the Mausoleum Clerk career, she is on track to becoming an Epitaph Writer.
