Bella Goth

Bella Goth was one of the pre-made Sims shipped with the original "The Sims" game, in which she lived with her husband Mortimer and her daughter Cassandra. In The Sims 2, Bella no longer actually exists; however, her essence lives on in two ways.

Bella's dissapearence from the game is a major component to the backstory of Pleasentview, the neighborhood where her family lives. The story does not explicitly state what happened to Bella, although her husband and children and Don Lothario have memories of her being abducted by aliens. Many of Mortimer's memories involve Bella, as do Cassandra and Alexander's. On the family tree panel, Bella's face isnt greyed out. This indicates that the game considers her not to be dead.

Although the actual Bella is gone, Maxis created a likeness of Bella and used it as a townie in another neighborhood, Strangetown. You are right if you say that version isnt the real version as she has small differences but she is acknowledged by maxis as bella. The only was of sending bella to strangetown (without messing up the game code) was to create an new bella! So that's what they did! And they say the reason she cant remember anything is becuase she got abducted and got tested with.
