Philip Henry was one of Giles' friends from his Ripper days. He traveled from England to Sunnydale to warn Giles about the return of the demonEyghon. He was killed by the demon, who had taken possession of the corpse of Diedre Page.
Philip's corpse was taken to the morgue, where it was identified by Giles. Installed in Phillip's body, Eyghon tracked down Ethan Rayne to Sunnydale High and was trapped in the process. After breaking out, Philip's body collapsed into a pile of goo, while Eyghon took possession of Jenny Calendar.
