Andrea Yates's universe



Andrea Yates' World was an alternate timeline created by the Trickster when he offered Andrea Yates to live instead of Sarah Jane Smith. The timelines diverged in 13th July 1964, when Sarah (Andrea in the original timeline) fell off a pier and drowned. In the altered timeline, Andrea lived on 13 Bannerman Road, Ealing and had a successful career as a painter. Luke Smith did not exist in this world. Maria Jackson and her father Alan still lived on 36 Bannerman Road.

It was destroyed when Andrea took back her deciding of Sarah Jane's death instead of her's. The universe was rewritten and Andrea was killed. The only one's who could remember where Sarah Jane, Maria, Clyde, Alan and the Trickster. (SJA: Whatever Happened to Sarah Jane?)
