Rudy was a hunter and acquaintance of the Winchesters.
When Dean asks Sam if he's found any cases for them to work, he tells him there is only a kitsune working some truck stops outside of Boise, but that Rudy is working on it. While Sam is out, Dean places a call to Rudy asking if he needs any assistance, which Rudy declines. He ends the call asking how Dean is doing, which Dean replies he is "fan-damn-tastic."
Angry at Sam for the death of Charlie Bradbury, Dean sends Rudy some security footage of a black sedan, so he can track down the Stynes and get revenge. While Rudy is able to find out that the car is registered to Eldon Styne out of Shreveport, Louisiana, he cannot produce an address. After Dean thanks him for his help, Rudy asks him why Sam couldn't get the information, only getting the answer "he's busy" from Dean.
Rudy calls in Dean to help on a "fangbanger" case, when the body of a young woman is found with her throat ripped. However, due to the Mark of Cain, Dean's demeanor has become more aggressive, and he tells Rudy he should go home and leave the killing to a "real hunter." Deciding it's not worth it to work with Dean, Rudy splits off on his own.
As Rudy is grabbing a machete from his trunk, he places a call to Sam telling him about Dean's attitude issues and where he can locate him. He gets to the cabin where the vampires are staying, and feeding on Crystal Thorrson, but is captured and beaten. When one of the vamps goes to wash the blood from his hands, Dean arrives and quickly decapitates him. When he enters the cabin, he finds Rudy being held at knife point by the other vampire Reggie. When Rudy attempts to talk his way out of the situation, Dean tells him to just leave as Reggie doesn't have the guts to kill his only insurance. Tension begin rising as Dean is egging Reggie on to stab Rudy, to prove to Rudy he can just walk away. Dean's plan back fires, and Reggie drives the knife into Rudy's chest, killing him. As Rudy's body hits the floor, Dean quickly goes in for the kill and unties Crystal, who accuses Dean of letting Rudy get killed.
Later on in his motel room, while Dean is washing his hands, he seeing a flash of bloody and beaten Castiel in the mirror, followed by a bloody and angry looking Rudy. Causing Dean to destroy his motel room.
