Sharon was a schoolgirl living in the English town of Blackcastle. She and her friend, Fudge, found the alien criminal Beep the Meep following the crash of his spacecraft, and were duped into helping him escape from his pursuers, the Wrarth Warriors, a police unit from the Wrarth Galaxy. Betrayed and threatened by the Meep (who attempted to turn Blackcastle into a Black Hole), Sharon was saved by the intervention of the Time Lord known as The Doctor. After an unwitting detour in time and space on the way back to Blackcastle in the Doctor's time machine the TARDIS, Sharon elected to join the Doctor on his travels. Shortly afterwards, Sharon was forcibly aged four years when the Doctor's TARDIS went through a space-time rift and had to bring two halves of it back together. Following several adventures with the Doctor, Sharon eventually fell in love with an artist named Vernor Allen on the planet of Unicepter IV, and elected to begin a new life with him since, having aged into her early twenties in the meantime, she felt she could not return to Earth and her family.
