At their motel, or possibly hotel -- Sam researches a plant clipping, and fails to notice his shout-out in the title card: "It's the Great Pumpkin, Sam Winchester." Dean comes in, mouth full of candy. Sam laughs at him. "Really? After that guy choked down all those razor blades?" Dean doesn't mind talking with his mouth full. "It's Halloween, man." He shoves another piece in for good measure. I think he has an oral fixation. The Dean Girls approve. Sam cracks that everyday is Halloween for them, but Dean tells him not to be a downer, which is about as effective as telling Dean not to eat the candy. Sam confirms they're on a witch hunt, but they're dealing with a powerful witch -- one with more juice than they've dealt with before. The hex bag contains Goldthread -- an herb that's been extinct for 200 years (close, but no cigar); a Celtic coin or medal that's approximately 600 years old; and the charred metacarpal bone of a newborn baby. Dean, of course, is sniffing the bone as Sam identifies it. He throws it down, exclaiming how gross it is. Witches skeeve Dean. Sam tells him to relax -- it's at least a hundred years old. Sam, I don't see the lab equipment you used to carbon date the bone. Did you leave it in Metallicar's trunk with everything else, or did you do it WITH YOUR MIND?!? Sam asks Dean if he found anything new on the victim. Dean says, "This Luke Wallace? He was so vanilla, he made vanilla seem spicy." They can't figure out why anyone would want him dead.
At a pre-Halloween party, a teen named Tracy and a teen named Jenny seem to be competing for the skimpiest costume award. Jenny's dressed as a "nurse" and Tracy's dressed as a "cheerleader." Do your parents know you left the house dressed like that? Brunette Jenny, who looks a little like Miley Cyrus around the eyes (but has more on) thinks the party is lame, but Tracy turns on her brightest smile for Justin, who seems to be the host. He can't break into his parent's liquor cabinet -- it's triple locked. He asks the girls if they're going to the mausoleum party "tomorrow night" at which he's going to get "so baked!" They're game -- they also seem to be competing for Justin's attention, and so far Tracy (the blonde) is in the lead. She spies a plastic tub full of apples, gets down on her hands and knees, bends over, and goes bobbing. When Jenny realizes how much Justin appreciates... the view, she takes a turn, but can't get any apples and can't lift her head up out of the tub of water. As she struggles, the water starts to boil. Eventually, Tracy and Justin realize she can't right herself, and try to save her, but they can't pull her head out of the tub until she's dead.
