Biography

The fortune teller once offered to foretell Donna Noble's future, but instead seemed more interested in manipulating her past. Her suggestion that Donna should turn away from her fateful first day at H.C. Clements forced Donna's past to change, and created a parallel world in which the Doctor was killed during his encounter with the Empress of the Racnoss. (DW: Turn Left)

After Donna, with the aid of Rose Tyler, was able to restore the timeline through time travel, she fled, terrified that Donna had managed to overcome the Time Beetle. According to the Doctor, the Time Beetle was part of the Trickster's Brigade making it likely the Fortune Teller was also.
