Like his teammates Riley Finn and Forrest Gates, Graham leads a double life with his military service and his cover up as a student at UC Sunnydale. But unlike his teammate Forrest, who is a rather brash person, Graham is more calm and collected. Graham did fight in the final battle in The Initiative and later testified in Riley's favor during the inquiry.
Later, Graham helped Riley get medical attention that would correct the procedures that the Initiative conducted on him. Graham later asked Major Ellis to help persuade Riley into leaving Sunnydale, to rejoin the army, as a part of their new squad of demon hunters, with himself and others, since he tried and failed to convince Riley himself.
