Helo’s Connection To Sharon ‘Boomer’ Valerii
The reimaginedBattlestar Galacticafirst introduces audiences to Helo’s relationship with Lieutenant Junior Grade Sharon “Boomer” Valerii, a concealed Cylon agent implanted with fabricated memories of her upbringing in the mining colony Troy. In the two-part episode “Kobol’s Last Gleaming” (season 1, episodes 12 & 13), Commander Adama entrusts Boomer with a perilous mission: the obliteration of the Cylon basestar encircling Kobol. However, her return takes a shocking turn as she wounds Adama, pushing him into a coma and unveiling her true nature to the entire crew. This revelation leads to her confinement in the brig, where the manipulative Gaius Baltar coerces her into disclosing the count of hidden Cylon agents within the fleet. Tragedy strikes during Boomer’s brig transfer when Cally, a crew member, fatally shoots her.
The episode “Downloaded” (season 2, episode 18) resurrects Boomer’s consciousness within a fresh Cylon body on occupied Caprica. Resistant toembracing the Cylon agenda, she strives to sway her fellow Cylons toward a more harmonious coexistence with humans. In “The Eye of Jupiter” (season 3, episode 11), Boomer cares for Hera, Athena’s hybrid child, in a Cylon base ship. Tensions flare between Boomer and Athena as they dispute the sincerity of human negotiations, culminating in Boomer’s demise at the hands of Caprica Six, who perceives her as a threat to the child’s well-being.

Boomer’s journey continues with another resurrection, forging an alliance with John Cavil, a Number One Cylon who embraces his mechanical identity, regarding human attributes as vulnerabilities. Their partnership solidifies during a deadlock among Cylon models regarding the fate of the Raiders. However, Boomer’s allegiance shifts during the Colonial attack on the Cylon colony, leading her to oppose Cavil’s intentions.
Helo’s Relationship With Sharon ‘Athena’ Agathon
Athena, a self-aware Number Eight Cylon, adopts the persona of Boomer to assist in a complex Cylon experiment. This experiment revolves around engineering a romance with Helo, intended to culminate in his demise. Gradually, Athena’s initial masquerade evolves into genuine affection for Helo, prompting her to defy her original programming. This internal transformation becomes evident as she aids Helo’s escape from captivity, ultimatelyunveiling her true identityto him. Athena’s confession not only lays bare her emotions, but also her pregnancy with Helo’s child – an unparalleled Cylon-human hybrid. Leveraging her knowledge of the Tomb of Athena on Kobol, she secures her survival and commits herself toprotecting the group from Cylon assaults.
However, her presence among Galactica’s personnel is strained due to the historical actions of the original Boomer. Athena, resolute in asserting her individuality, clarifies her distinct consciousness, separate from her predecessor.Athena’s pregnancy sparks conflict as President Roslin initially contemplates termination. However, the fetus’s unique blood properties hold potential to cure Roslin’s terminal cancer, leading to a reversal of this decision. Athena delivers her child, Hera, prematurely. Despite reservations, the Colonial administration orchestrates a ruse, placing Hera with a human family while feigning the child’s death. This strains Athena’s loyalties, yet she remains dedicated to aiding the Galactica and its crew.

Athena and Helo solidify their bond in marriage during the interval between season 2 and season 3. Earning Admiral Adama’s complete trust, Athena attains the rank of Lieutenant Junior Grade and assumes an officer’s role in the Colonial Fleet. Tasked with facilitating communication between the Galactica fleet andthe New Caprica resistance, Athena’s dual identity as a humanoid Cylon allows her to infiltrate the Cylon base, securing crucial resources for the civilian ships.
As Colonial negotiations with the Cylons ensue, Athena and Helo make a startling discovery: their daughter remains alive aboard a Cylon vessel. Athena embarks on a mission to retrieve her child, leading to a confrontation with Boomer. In a poignant act of contrition, Boomer permits Athena to end her life, marking a somber closure to their complex entanglement.
