Working with the First Doctor and Steven Taylor, she defeated the Daleks. Unfortunately it caused her to be time-destructed and she died horribly. In between those wacky adventures Sara also became a house, went to Seaworld and cried about her brother inside a giant clock. Eventually the poor sod listening to her go on and on about these totally canon stories decided to ring up one of the Doctors and made him pick her up again. She died again shortly later of a cold.
