Graham Miller was one of Riley's two closest friends, along with the late Forrest, and he lived in the same dorm as the two of them. He was also part of Riley's commando squad in the Initiative, and helped Riley on several missions, including the attempted recovery of Hostile 17 — Spike. A man of few words, he rarely opened his mouth except to impart dire news or the occasional wisecrack. Unlike Forrest, he supported Riley with regards to Buffy, saying that he liked her, and often seemed to find the ardor of their relationship amusing. Graham survived the destruction of the Initiative, and apparently defended Riley at a debriefing about the failure of the project. He turned up again as part of a secret government unit which fights demons, and he successfully persuaded Riley to join this unit on their next mission somewhere in Belize. His current whereabouts and condition are unknown.
