She implanted herself in Kianna Cyr to learn more, and began a relationship with Jonas Quinn. She also supplied a great deal of Goa'uld technology to the Deep Underground Excavation Vehicle, increasing its efficiency.
Major Samantha Carter realized who she was, but there was no hope of operating it without her. She was apparently in a relationship with Jonas Quinn at the time of her discovery and revealed that his relationship had always been with the Goa'uld and not the host. This Goa'uld apparently did harbor real feelings for Jonas, but he was disgusted by her when he learned the truth. Part of her motives for what she was doing was she wanted the Naquadria for herself and, based off a comment, wanted to use it to make her own empire.
She helped pilot the DUEV and when the time came for someone to crawl down into a tunnel to plant the bomb, offered to do so as being a Goa'uld would protect her from the radiation for a while. She successfully completed her mission, but due to power draining and knowing she "probably wouldn't survive anyway", insisted the others leave without her. Jonas refused and she made her way to the ship where it was indicated Jonas had real feelings for her too. She was taken to Stargate Command and treated, but her radiation exposure was just too much and she died. Interestingly, she saved her host's life, a deed common among the Tok'ra, but rare among the Goa'uld. Kianna said that the Goa'uld appreciated what SG-1 and Jonas had tried to do for her.
