Lucy Cain was Helena Cain's younger sister and was killed by the Cylons during the first Cylon War.
Tauron was under attack by Cylon basestars and Centurion ground forces on the last day of the war. Lucy, her sister and her father were pinned down in a building under heavy fire. When her father is injured trying to escape, he tells Helena to get Lucy to a shelter. The two make it out of the building, but outside Helena panics, leaves Lucy in a field of rubble and runs away to hide in a container. When Helena comes out again after the Cylons retreated, she finds only her sister's doll on the ground (Razor).
