Sharon believed she was a well-liked Raptor pilot (callsign "Boomer") until her true identity as a Cylon infiltrator was revealed. That copy of Sharon was killed on the Galactica (and resurrected on Caprica), but a different avatar of Sharon fell in love with Karl "Helo" Agathon and aided the humans against the Cylons on New Caprica, earning Admiral Adama's trust and winning a commission as an officer and pilot in the Colonial Fleet; she flies under the callsign "Athena." Athena and Helo are married and have a daughter, Hera, the first human-Cylon hybrid. Despite her loyalty to the humans, Sharon Agathon's origins still sometimes provoke tension among her colleagues and within her own mind. Meanwhile, other copies of Sharon — including the resurrected Boomer — continue to live among the Cylons.
The pirate Heracleo betrays team Spartacus, Caesar stabs Spartacus, Agron does an amazing spin down a rope, and Crixus and Naevia return to fight for the city. A real action packed sequence.
Caesar: spreading news and making everyone hate each other. When Crixus gets wind of his tale, he confronts Agron head-on.
