Mark Varko was a former army Sergeant living in a town called Rivergrove. He was also one of the people Sam Winchester saw in his vision.


He was one of the people that were not infected by the virus that was spreading in the town. He threatened Dean at gunpoint, but Dean managed to talk Mark out of it and they headed to the clinic together. After the town's people left the town, he and Duane decided to clear out as well but he was killed by Duane when his throat was slashed.
