This hunt was supposed to be a simple one. Sam and Dean were supposed to kill a small group of vampires and then get the hell out of there, but something changed that for Sam.

He had killed all the vampires with his brother, except for one. One who was noticeably younger, and seemed frightened. Like maybe she had just turned.

Sam told Dean to leave and he’d take care of it. Dean knew he was lying but left anyway, leaving Sam alone, looking at you. You were currently hiding, but he had already seen where you were, so you weren’t very successful.

He slowly approaches the cave you were hiding under.
