He was standing out by Dean as they worked on a case together, they were actually doing things together, though they thought domestic life is a great thing, and it was, it was better than they imaged, but they couldn’t let this hunt up, it was in the blood, to hunt.
Once they got to the location, they went in, not paying attention to anything, and while on the missing Dean cut got a cut on his hand. Now most times a cut wouldn’t matter, but since that cut would later bite Dean in the butt, it seems this one will. They went until they found a person and at first they didn’t realize it, but the place was being taken over by the Crotoan virus, and it just got into Dean’s blood. They saw the people but then they started charging after them and they quickly ran for cover, and once they found a place to hide they looked at Dean’s wound and cleaned it up. Dean had been a little dizzy so he let his lover rest and went out for a walk.
While out on the walk he found a telephone pole with Croatoan carved onto it. He pointed to it, and looked around for anyone, trying to see if anyone, that was still around, even knew about the pole.
That was when it hit him, Dean, his lover was infected by the virus, there was one thing he didn’t do and that was go back to where they were hiding out, he went over to the area he found all the people and pulled out two guns and started shooting them all down. Once he had killed everyone that he could find in that area, he went back to the hiding place and walked over to Dean.
He started to cry, his lover was going to die because of a fucking virus that he’s fought before, only then it didn’t involve him and his lover. He leaned down and kissed Dean on the lips, only Dean didn’t wake up, but Dean did still have a pulse, he felt the heat from Dean’s body. He whispered to Dean softly. “I love you.” And little did he know Dean was able to hear that and he heard “I love you too.” He kissed Dean again and then waited until Dean went back to sleep and closed his eyes and started to cry, he shook his head and pulled himself together. He needed to see to do this. He pointed the gun at Dean’s head and closed his eyes and shoot Dean. And like that he took his lover’s life. He leaned down and kissed Dean, and kissed Dean on the lips and closed his eyes, and shot himself in the head. He didn’t want to be without Dean, and before he died, he made sure to grab Dean’s hand and lace their fingers, so when they are found, whoever finds them, will know they loved each other, and the thought of going on without the other was to hard to handle.
Just like that, a hunt took both of them, it infected Dean, his lover. And he couldn’t handle being without Dean, because he made a promise to Dean, and that was to always, be with Dean. And he made sure of that.
