Her first major operation was TREBUCHET, having infiltrated a United Rebel Front faction on Hectate, she posed as a young intelligence officer while feeding information to the UNSC forces ahead of their strikes and aiding the escape of SPARTAN-013 from the facility. She was not seen again till the Battle of Morigan III where she was taken prisoner by the Covenant forces who marauder through the facility she operated in. She and two her fellows were tortured for information but she held out until the Spartans of Black Team rescued her. After sometime of operating, she was caught out again by the Covenant, being caught in CASTLE Base during the battle of Reach. With her transport off world destroyed, she decided to make use of an old ONI base to try and evacuate with her ONI staff but found the Chiroptera-class Stealth Vessel there was decommission. By chance, she happened upon SPARTAN-013 and SPARTAN-038 and used his prodigous techincal skill to fix it before escaping. Once in orbit she and the others were picked up by one of her old comrades, CaptainZachary Drogen.
