Victor Henriksen

Victor Henricksen was an FBI agent whose job was to track down and arrest the Winchester brothers. During the course of the series, Henricksen was able to arrest Sam and Dean twice.

Season 2
Agent Henricksen appeared for the first time in the episode "Nightshifter", where he took charge of local police in an attempt to free the people supposedly taken hostage by the Winchester brothers. Henricksen was confident that he had Sam and Dean cornered, but they escaped. Later, in the episode "Folsum Prison Blues", Henricksen achieved in capturing the brothers, but it was an empty achievement, as the brothers set themselves up to be captured. By the end of the episode, Sam and Dean escaped yet again.

Season 3
In the episode "Jus in Bello", Agent Henricksen captured Sam and Dean again, this time because of a tip made by Bela Talbot. After he was possessed by a demon, which was exorcised shortly after by Sam, Henricksen believed that the Winchester brothers weren't murderers afterall and he let them go, making it seem that they died in a fire. After Sam and Dean left, Henricksen was killed by a demon named Lilith.

Season 4
Henricksen appeared again in "Are You There God? It's Me, Dean Winchester" as one of the Witnesses. Like the others, he tortures Sam and Dean on their inability to save him, and explains that Lilith tortured them for 45 minutes before finally killing them. He is later banished, along with the other ghosts, by Bobby's ritual.
