As part of his plan to create a new generation of "better" hunters, Victor Rogers hires the vampire Seth to turn innocent people so that Josephine Barnes, Aidan and Krissy Chambers will kill them, believing that they are the ones who killed their families when in fact it was Seth. To this end, Seth kidnapped this young woman, turned her into a vampire and left her in an abandoned lodge to be found by the three young hunters and killed.
In Freaks and Geeks, Victor showed Krissy, Aidan and Josephine a picture of this young woman and claimed that she was the vampire that murdered Krissy's father with the young woman even having a necklace belonging to Lee in the picture. However, Victor's claims draw suspicion from the Winchesters and Dean manages to track down the lodge the young woman is kept at before the three young hunters. After learning that she had been freshly turned and hadn't yet fed, Dean realizes that she is a victim of the true culprit as well and keeps Krissy from killing her, telling Krissy that as she has not yet fed, they can cure her if they can get her sire's blood.
