Chaz surprised his other team mates when he demonstrated a strong disliking of Elliott Parks, the first such occurrence being during the group's re-assignment to border patrol around the Temper system. At that point the other Knights suspected that there was a lot more to the two men's relationship that might otherwise appear.

Though he remained somewhat withdrawn, he went on to demonstrate intimate knowledge of starfighters and battleships, such as Dragon, briefing the flight groups on what they could expect during the commencement of Operation Menelaus.

Chaz ultimately went on to save the White Knights' lives when he helped them to escape from Arlos starport after retrieving the ATAF plans from CSS agent Clare Barber. It became apparent that Barber and Chaz might also share a past together.

Chaz was promoted to the rank of 1st Lieutenant following Griffin and Ifrit's successful return to Spirit.

Along with his fellow wingmates, Chaz was en-route to the Solaris system when CSN Ifrit was ambushed in jump by a Pandoran force. After the invaders forced the carrier from jump, the White Knights were evacuated to the surface of Mythos, to the city of New Malaga. Chaz made the journey to the surface of Mythos along with Estelle de Winter. Their sled suffered a mechanical failure when it was performing re-entry into the planet's atmosphere and eventually crashed in a park. Chaz dislocated his shoulder during the event, but quickly reset it.

He guided Estelle through the city to the coast, stopping briefly at a broadcast house for a news station known as Cielo, to attempt to establish communications with the CSN. Chaz revealed himself to be a spy, working for the Confederation Secret Service, having been in their service for a number of years before joining the White Knights.

He saved Estelle's life during the battle of Hunter's Square, preventing her from being crushed under a pile of falling rubble. During the battle, he displayed great prowess with a plasma rifle, preventing the Mythos Territorial Guard from being overrun when he overcharged the weapon, to discharge its remaining output in a single shot.

He later revealed that, not only was he married (to Vanessa Koonan), but he was a father to one boy named Matthew, with his second son (Luke) due within months. He had never joined the CSS willingly, having been coerced into doing so after being caught selling black market good by the CSN. He spent several years working as an intelligence officer in the Mitikas Empire, gathering data on the fallout between the Crown Emperor and the Senate, being one of the first to learn about the super soldiers who would go on to become known as the Pandoran army. During that time, he worked extensively with Claire Barber, as well as having irregular contact with Natalia Grace.
