Porl had had an unhappy relationship with a woman named Rebecca. 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 Benny confronted him, he had the ring. She started hitting him until Anderson pulled her away. To Porl's dismay, she took the ring and dropped it, breaking it. (PROSE: Step Back in Time)
