Sarah Jane Smith (Donna's World)

Sarah Jane Smith had her life changed for the worse on 25 June 2007, when Donna Noble turned right instead of left; this small change in affairs produced Donna's World.

Sarah Jane was investigating the Royal Hope Hospital - along with her son, Luke Smith, and his friends, Maria Jackson and Clyde Langer - when it was transported to the Moon.
