Rebecca (Step Back in Time)
From Tardis Wiki, the free Doctor Who reference
Rebecca was a woman who had had an unhappy relationship with Porl Tomas. He went to the Braxiatel Collection to find a stone ring that would allow a person to go back into his past in order to change things. He used Bernice Summerfield, pretending to be in love with her, to gain access to the stone ring. When Bernice confronted him, she broke the ring, and he was unable to change his past with Rebecca.
