Sarah: "It doesn't say kill Sam!"
Sam: "It says the blood of a virgin!"
Sarah: "Doesn't mean a dead virgin!"
Sam: "Duh . . . but it still wants the blood, and most powerful spells require lots of blood Sarah! How do you even know this will work! We don't even know what's really wrong with Dean!"
Sarah: "I think that's kinda obvious Sam."
Sam: "Oh, please, enlighten me, cuz I'm not getting the whole picture here! his voice dripping with disbelief and a little sarcasm."
Sarah: "Look, you told me he figured out you guys got switched right? Well it's obvious his body is fighting against the part that doesn't belong in him. It's like when out bodies fight back against an infection or a disease or something. It's trying to kick that part out."
Sam: "So Dean's having a bad reaction to my personality?"
Sarah: "Basically . . ."
Sam: "And this spell . . . curse . . . whatever it is will fix this? Do you even know for an absolute fact if this will work? "
Sarah: "Nothing is ever absolute Sam . . . but I still think we should try it."
Sam: "Oh, well do you have a virgin for me? One who's willing to let me slash her open and use her blood?"
Sarah: "Yes."
Sam stares at her shocked.
Sam: "I . . . I'm sorry; I think I heard you wrong."
Sarah: looks annoyed. "No you didn't. You asked me if I had a willing virgin for you. And I do."
Sam: "You do. And uh . . . just who might this be?"
Sarah: "That doesn't matter right now. Fact is that it's the one ingredient we don't need to worry about."
Sam: "Ok and I guess you think I'm just gonna waltz outta here and be able to find all this other stuff?"
Sarah: "No one said it'd be easy Sam."
Sam: "Well no shit Sherlock! I . . . I haven't the faintest clue where to even begin looking for this stuff! I mean . . . black salt? Doves blood ink? Bone of an Ibis? A Snakes ball of thread? Sarah, what is all of this!"
Sarah: "I don't know Sam! But think about this . . . this IS the only way to save Dean!"
Sam: "No, Sarah, there has to be another way! I mean, this is just . . . impossible! Where in the hell am I supposed to find Blood of Hephaistos? Or . . . or Krono's Blood? Or what about A Bull's Semen! I amnot getting that one . . ."
Sarah: "Well, this is what we have to get Sam. You need to find all those . . . vulgar, ingredients. It's the only way."
Sam: "Ok . . . ok, say I can find all this stuff. What then?"
Sarah: "Uh . . . You'll come back . . . we'll set everything up, and we'll perform the ritual and save Dean."
Sam: pauses for a moment "But this could still totally screw up and go horribly wrong."
Sarah: "Yeah, but I'm willing to risk that . . ."
Sam: "So am I. I was just making sure we were completely clear on that fact."
Sarah: "Yeah . . . we're clear. So . . . we gonna do this or not?"
Sam: "Yeah, but Sarah . . . Who's the virgin?"
Sarah: levels her eyes at him, dead serious. "Me."
