'''Giana O'Neill''' is an aeronautical engineer employed by [[Sun Airways]] who, after winning a [[Caprican refugees|lottery drawing]], is rescued from {{RDM|Caprica}} by [[Sharon Valerii|Sharon "Boomer" Valerii]] and [[Karl Agathon|Karl "Helo" Agathon]] during the [[Fall of the Twelve Colonies]]. She enlists in the [[Colonial Fleet (TRS)|Colonial Fleet]], becoming a mechanic aboard ''[[Galactica (TRS)|Galactica]]'', replacing deckhands lost during the Fall.

== Joining the Fleet ==
She is brought to ''[[Colonial One]]'' via [[Raptor 312]], asking for her husband, and later appearing in the crowd at the [[service for the dead]] where Commander [[William Adama]] announces their destination, [[Earth (RDM)|Earth]] {{TRS|Miniseries}}.

Her husband [[Simon O'Neill|Simon]] served as a medic in the Colonial Fleet near [[Gemenon|Gemenon]] and was presumed dead {{TRS|Miniseries|The Plan}}.  She has a daughter, [[Jemmy]], from a previous marriage.

O'Neill enlists in the Colonial Fleet and becomes a mechanic on ''{{RDM|Galactica}}'', putting her civilian experience as an aeronautical engineer to use.  She bonds with Chief [[Galen Tyrol]], and immediately picks up on his relationship with Valerii, stating she knows an "office romance" when she sees one.  She is reunited with her husband and daughter, who managed to get off Gemenon aboard the container ship ''[[Cybele]]''.  

Unbeknownst to her, Simon is actually a [[Number Four]] [[Humanoid Cylon|Cylon]].  He later commits suicide when he is ordered to blow up ''Cybele'' by Brother [[John Cavil]], choosing to die rather than hurt the ones he loved with the belief that his love for his wife would outlast his death. O'Neill is questioned regarding the incident by Colonel [[Saul Tigh|Tigh]]. During the questioning she brings up and then denies the possibility that Simon was a Cylon. Tigh assures her that no one thought he was and conveys his sympathies for her loss. After later learning from [[Kara Thrace]] that Simon was indeed a Cylon, O'Neill discusses the matter with Tyrol. She claims Simon's suicide was heroic, and she'd also kill herself if she suspected she were a Cylon too {{TRS|The Plan}}. This later prompts Tyrol to ponder and attempt suicide himself following his discussions with Brother Cavil and Valerii's earlier death {{TRS|Lay Down Your Burdens, Part I}}. 

O'Neill appears one last time as she stands in an intersection while the Cavils are being escorted to the [[hangar deck]] for their execution via a [[Launch tube (TRS)|launch tube]] {{TRS|The Plan}}.
