At one point in her life, Anges was a part of the Spartan-II project. During the project, she developed a romantic relationship with Professor Mike. Together they had a little girl who, for unexplained reasons, died. Sometime afterwards, she and Mike broke up. Both she and Mike knew elements of the Spartan program that were done that Halsey didn't even know about. When Ralph-303 and Daisy-023 died, Mike wrote a letter to her, explaining that she needs to think about Ralph and other elements when working on "new children."
- News of the Spirit of Fire's encounter with the Flood may have reached ONI by unknown means. Mike and Agnes may have had high enough clearance to know about the Flood. In a letter from Mike to Agnes, Mike mentions the "Flood" anomaly as a path of least resistance.
- Agnes may be in charge of the Class-II of Spartan-IIs, as Mike knows that she is working with "new children." He told her that when not teaching and monitoring them, she is to be a mother to them.
