She recognizes crew-member Jean Barolay as a resistance fighter from New Caprica who gagged her, threw her into a septic tank and watched her drown, an event that has left her emotionally traumatized.

Shortly afterwards she is shot and killed by another Six copy, Natalie who does it to give the Colonials "justice" since there is no Resurrection Ship in range.

Casting Tricia Helfer was cast after a strong audition, despite some initial concerns over her lack of acting experience. Director Michael Rymer explains: "It wasn't just the way she looked; she just has this vibe about her. Nobody gets how hard that role is, to bring the depth, the vulnerability and the mystery to essentially a robot chick." Among the other actresses who auditioned for the role were Melinda Clarke and Leah Cairns, who went on to play Racetrack. Reception In 2006, Tricia Helfer was awarded the Leo Award for "Best Lead Performance by a Female in a Dramatic Series" for her role as Number Six in the episode "Pegasus".
