Well, that was something pleasant. His ears ringed as the blast went off and he crumbled to the ground along with the vampire's body, the older Winchester paying more attention to his ears than the fang marks in his neck.

"So...what the hell are you doing here?" Last time he saw her, she was in Duluth and it wasn't under the most pleasant circumstances. The question, however, hid his grateful tone from the huntress.
