Sharon and Helo are married in the year-long gap in events between Season 2 and Season 3, and, having earned the full trust of Admiral Adama, Sharon is sworn in as an officer in the Colonial Fleet at Boomer's rank of Lieutenant JG. She is sent back to New Caprica as the liaison between the "Galactica" fleet and the resistance effort, and, due to the inability of the Centurions to recognize individuals within the humanoid Cylon models, is able to infiltrate the Cylon base and steal the keys for the civilian ships. After the successful rescue mission, Sharon receives a new call sign: Athena.
