Sam and Dean were on a run of the mill vampire case. They were currently in an old abandoned shack, fighting and trying to kill the vampire nest.

Sam was fighting off one vampire, trying to cut its head off. "Damnit!" He muttered as he struggled against the vampire.

Dean was fighting another vampire, trying to avoid being pushed back or killed. What he didn't know was that there was a wooden post behind him, with a nail sticking out that could kill him if the vampire pushed him in it.
