In order to lure in the vampire that killed Aiden's family, Krissy and Aiden pretend to be a couple that are trying to make out at a local make-out spot in Conway Springs, Kansas and the vampire attacks them. While the vampire is distracted with the supposedly frightened Krissy, Aiden decapitates it from behind and confirms that it was the one that killed his family. Unknown to them, they are caught on a nearby security camera and the cops start looking for them until Dean gets them to call off the search.
Krissy checks into a motel, bribing the clerk to accept her fake ID, and meets with Aiden and Josephine Barnes about Jimmy Day, the vampire that killed Josephine's family. Aiden flirts with her, but Krissy rejects his advances, claiming to have a boyfriend in Canada that she talks to on Skype. Using ATM footage, they have tracked Jimmy to that motel and Krissy watches through cameras worn by Aiden, as he and Josephine travel to Jimmy's motel room. When two men break in, Krissy holds them at gunpoint and is shocked to see that it is Sam and Dean and that they tracked her down. Seeing from the camera that Aiden and Josephine are in trouble, Krissy, Sam and Dean rush to their aid and when Jimmy runs, Krissy takes him down with a dart loaded with dead man's blood. Jimmy claims to be innocent but Josephine kills him.
At their home, Krissy introduces Sam and Dean to Victor Rogers. The next day Victor pulls them out of school early and shows them a picture of the vampire that he says killed Krissy's father, which he said is proved as she is wearing Krissy's father's necklace. Krissy, Aiden and Josephine take off to hunt it down.
Arriving at the abandoned Conway Springs Lodge, the trio find Dean and the vampire and hold guns on him, insisting on killing her. However, Dean reveals that she is an innocent victim and something else is going on. Dean easily disarms Aiden and convinces the kids to find the real vampire behind all of this as with his blood, they can cure the young woman.
Returning to Victor's house, the group finds Sam tied up, Victor with Seth, who is a vampire. Sam and Dean reveal what they have figured out: Victor has had Seth kill their families to drive them into hunting so he could train the next generation of hunters, having them get "revenge" by killing people who have just been turned and he has framed. When Krissy asks who the real killer is, Seth informs her that he killed her father and enjoyed it. Victor disarms himself and tries to convince the group to keep going with him, but they refuse and he has the vampire take Aiden as a hostage so he can escape. Krissy shoots Seth in the right eye and chest with darts filled with dead man's blood, saving Aiden. She then pulls a gun on Victor, threatening to kill him. Krissy decides that having Victor live a lonely life with no one will be revenge enough, but he kills himself instead.
Later, as Aiden and Josephine give the cure to the victim they rescued, Krissy says goodbye to Sam and Dean - she, Aiden and Josephine will continue to live together and Dean decides to have Garth check in on them from time to time. Dean suggests to Krissy that she has a crush on Aiden, which she denies. Dean gives Aiden some advice, warning him that if he hurts Krissy, "she'll kill him".
