This unnamed demon infiltrated the FBI in an effort to get at the Winchesters.
At an unknown point, this demon possessed FBI Deputy Director Steven Groves, presumably in an effort to use the agency's resources to get at hunters Sam and Dean Winchester. At some point during this possession, Groves died of an unknown cause though the demon continued to possess his body.
During his hunt for the Winchesters, Agent Victor Henriksen reported to what he believed to be Groves but was in fact this demon. After capturing the Winchesters in Monument, Colorado based on a tip from Bela Talbot, Henriksen called "Groves" to let him know that he had captured the Winchesters and intended to transport them via bus to Supermax. The demon refused to risk losing the Winchesters again and instead decided to come personally in a helicopter to transport them.
Arriving at the sheriff's station, the demon handed Henriksen some paperwork to complete and then went to see the Winchesters. Gloating at their capture, the demon drew a silenced pistol and shot Dean in the shoulder. Before he could fire again, Sam grabbed the gun and struggled with the demon for it. After the demon turned Groves' eyes black, Sam realized he was possessed and began an exorcism. In great pain, the demon told Sam that he hated to cut the fight short but "its gonna be a long night fellas." The demon then vacated Groves' body through a vent before Sam could complete the exorcism, leaving Groves dead on the ground.
Following his escape from Groves, the demon alerted around thirty others of the Winchesters presence, leading to the destruction of the helicopter and the deaths of its pilot, four deputies and Agent Calvin Reidy.
The demon eventually returned to the station and possessed Henriksen himself in another attempt to get at the Winchesters directly. In Henriksen's body, the demon shot Sheriff Melvin Dodd, but was grabbed by the Winchesters before he could do any more harm. Having turned their toilet water into holy water, Sam shoved Henriksen's head into it and began performing another exorcism while Dean held off Deputy Phil Amici. While the demon struggled, the holy water kept him from escaping and Sam was able to complete the exorcism. Before being returned to Hell, the demon warned the Winchesters that it was too late as he'd called for help and they were on their way.
After the demon was exorcised from him, Henriksen finally came to believe that the Winchesters were telling the truth about monsters and demons. As a result, Henriksen began aiding the Winchesters against the coming demon threat.
