Two Different Kinds Of Hunter (SuperGrimm Crossover)

Dean and Sam Winchester are on the road once more. They decide to stop at a motel for the night to rest from their hunt. Sam being...well Sam he takes out his computer for research. He comes up on a article about an "animal attack" in Portland Oregon. The article states that there was no forced entry in the home of the victim. So how did this "animal" get in to the home? The first thing that popped up was a werewolf or hell hound. So the brothers hit the road once again to Portland. When they get there the first thing they did was head to the crime scene. Police were in and out of the house. The brothers easily got in and to the scene-which was the living room on the couch.
"Detectives. The feds." Said an Officer.
"Greaatttt." Said a heavy voice. And two men turned around. One black with a sarcastic face on. And the other...
Cream skinned, brown hair, green eyes, strong jawline, actually shorter than Dean.
And his name was Nick Burkhardt.
