Aidan and the only one of the three I find tolerable are still negotiating the lock on the door as Krissy explains to the Winchesters that they're hunting a vampire. She shows them her computer screen just as her two friends get into the room. A woman lies gagged and tied to the bed. "Nobody here but a vic," says my favorite with no sense of urgency. She and Aidan look down at her for a while, like, go ahead and take your time, dipshits. But if they had hurried to save her, then they wouldn't have crossed paths with the hissing vampire that shows up to pounce on them. Sam and Dean hightail it to the room, guns drawn. The vampire bares his teeth at them, and then takes a flying leap out the nearest window. Dean sees him running towards a blue van parked at the curb. "I got him," Krissy says, running down the hall. Dean chases after her. Meanwhile, Sam's quite frantic to get some help for the woman in the bed, but the kids have already called an ambulance.
Dean catches up to Krissy outside just as she gets the vampire in her sights. "Please, don't shoot me," the vampire begs. She shoots him anyway, and down he goes. "How'd you drop him so quickly?" Dean pants. "Dart's filled with dead man's blood," she says. Dean struggles to catch his breath, even though he regularly runs and fights tons more than this without breaking a sweat. "Where's the blue van?" Dean gasps. Krissy has no idea what he's talking about, so he adds, "The blue van he was Usain Bolt-ing it to." She still doesn't know what he's talking about, so he gives up and takes out a knife. As he advances on the prone vampire, Krissy stops him. "This is not your kill," she says. The rest of the Scooby gang joins the party. The as-yet-unnamed teen girl does her version of Inigo Montoya's intro. The vampire seems a bit confused when she accuses him of killing her family some months ago. "I didn't do anything, I swear," he says. "Please, help me!" Sam and Dean look a bit confused, too, but the teen girl raises a machete and lops off the vampire's head. Gee, I hope nobody was looking out the motel windows during all that ruckus.
"It's okay," Krissy says to her friend. "It's over." Dean calls Krissy to the side to have a chat with her. Aidan bubbles with envy. "You know this guy?" he asks. "Yeah, we have a past," Krissy says. So she and Dean have a talk about how she and her dad had a great life for a while, dinner every night, went on walks. "And then the past came a-knocking," she says. "I woke up one morning and found him dead, his throat ripped out." Dean offers his condolences and sad music plays, but Krissy seems so blasé about the whole thing in a way that goes beyond a facade of teen toughness. "If it hadn't been for Josephine and Aidan, I don't know how I would have made it," she says, explaining that the same nest of vampires killed their families, too. Dean tries to talk her out of continuing the hunt, telling her that hunting is more than just killing and revenge. It's also about endless bickering, passive-aggressive pouting and crushing self-loathing! "Do you have any family still out there?" he asks. "An aunt in Cincinnati," she says. Well, Dean wants her to pack up and go there right now, but Krissy says Victor would have a problem with that. Victor, she says, is the one who took them in and taught them everything they know. "Are we talking about some kind of kid school for hunters?" Dean asks. "Don't be such a dweeb," she says. "We're not the X-Men; Victor's helping us get revenge." Dean points out that Victor's not exactly doing a great job, seeing as how the kids caught. "If it wasn't for me, you and your friends' faces would be splattered all over the news," he says. "Well, so what?" Krissy snits. "Maybe it's time that people knew the truth about what's going bump in the night!" Dean thinks that would just cause panic, but it's not like people went especially nuts when Castiel took his smitey god show on the road. The show just doesn't have the budget or scope to deal with mass reactions.
