Battle of Installation 04
Frye was able to escape the Autumn along with the rest of Echo 419's air crew - including Rawley and Cullen - as it was shot down over Installation 04. He would proceed to fly with her throughout the Battle of Installation 04. Frye was present in Echo 419's cockpit during the outbreak of the Flood at the Flood containment facility on September 20, where he was able to exclaim his surprise at the surprise appearance of Aggressor Sentinels in the facility swamps.
Frye's fate following September 20 is uncertain, though he was presumably killed by the time of Echo 419, and Installation 04's, destruction on September 22.
Personality and traits
