Dean's POV
As Dean let off the second of his arrows, he saw Sam running down the hill according to plan. But then Dean saw the head vampire approaching Sam from his blind side. Dean started running down the hill for all he was worth. He had to beat the vampire to Sam.
When he was only halfway there, he saw the vampire knocking Sam down, the machete flying out of his hands. Dean noted where the weapon fell and increased his pace. He hadn't thought that was possible. He reached the machete, bent down to pick it up and when he turned around to go after the vampire, he was met by the sight of the vampire with Sam in a tight choke hold.
"Don't, or I break his neck," the vampire threatened.
Dean froze. He had never been so scared for Sam in his entire life. This was the first time anything or anybody had actually used Sam as a shield.
"Drop the blade," the vampire commanded.
Dean just stood there. If he dropped the blade, Sam was still dead and so were he and his father. The vampire noticed his hesitation and increased the pressure on Sam's neck. Sam let out a pained grunt and his eyes closed as his hands fell away from the vampire's arm. Dean decided to drop the blade in the hopes the vampire would ease up on the pressure a bit. He took his right hand away from the blade and held it in front of him in a non-threatening gesture. He then leaned over and let the machete fall to the ground.
"Please," Dean said.
The vampire let up on Sam just a bit. Although Sam seemed to be unconscious, Dean could see that he just took in a huge breath of air. Dean was concentrating on Sam, and he almost missed that the vampire was saying something.
"You people, why can't you leave us alone?" We have as much right to live as you do."
Dean wasn't sure how to answer that. What answer would get Sam released safe and sound? He was still pondering that when the alpha female spoke up from behind him.
"Luther, the other one's awake."
Dean saw Luther turn in the direction of his father, but Dean's eyes never left Sam. He was afraid if he stopped looking at Sam, he would stop breathing.
"Why don't you come on over and join your friend," Luther invited.
