Jodi Melville, a friend of Pete's, drinks health shakes made with Kryptonite-laced vegetables and becomes thin as a result, but also begins craving the body fat of others. Lex becomes intrigued by Chloe's theory about the meteor rocks in Smallville, and pays a visit to Dr. Steven Hamilton, a reclusive mineralogist.
Tropes present in the episode:
- Anti-Villain: Jodi just wanted to be thin and beautiful.
- Applied Phlebotinum: The vegetables that Jodi uses to make health shakes are laced with Kryptonite fragments; this causes Jodi to rapidly lose weight but to also start craving the fat of others.
- Asshole Victim: Dustin, who bullied Jodi for being obese early in the episode, gets his fat sucked by his former victim.
- Big Eater: After the Kryptonite shakes start to work, Jodi starts to devour anything she can find in her kitchen. By the time she is done eating, the kitchen is a mess. Later, when talking to her dad through her bathroom door, her bathroom is littered with junk food wrappers and a large empty pizza box. Clark and Chloe immediately notice her ravenous eating habits at the school cafeteria.
- Body Horror: Dustin, after Jodi sucks the fat out of his body.
- The Bully: Dustin teases Jodi for being fat.
- The Dog Bites Back: Jodi gets her revenge on Dustin by sucking his fat.
- Gone Horribly Right: Jodi starts a vegetable-shake diet to lose weight, and inadvertently uses plants laced with kryptonite for the base. She indeed starts shedding pounds rapidly, but the plan works too well and leaves her craving food nonstop—to the point of needing to eat human fat.
- Growling Gut: After having her metabolism affected by the Kryptonite shakes, Jodi's stomach continuously growls due to being left in a state of starvation if she isn't able to drain people's fat.
- Heel Realization: Jodi has one when she's about to kill Clark and she sees her reflection on the broken glass.
- Horror Hunger: Jodi's increasingly-rapid metabolism leaves her constantly hungry. At first she's able to sate the pangs with a stream of high-calorie food, but she's eventually forced to turn to freshly-killed animals and living humans to satisfy herself.
- I'm a Humanitarian: Jodi sucks the fat from others.
- Missing Mom: It's implied Jodi's mother passed away as both she and her dad talk about her constantly in the past tense.
- My God, What Have I Done?: Jodi says this when she knocks out Pete, almost kills Clark, and realizes what her kryptonite diet has done to her.
- Our Vampires Are Different: Jodi becomes a fat-sucking vampire.
- Pet the Dog: Everything Pete does for Jodi. Standing up for her when she gets bullied by Dustin, even before she lost the weight, and asking her out to Lana's party.
- Dustin gets a minor one when he sincerely asks Jodi if she's okay while she's experiencing her Horror Hunger.
- Rage Against the Reflection: After going on a binge in the kitchen and realizing what those weight loss shakes made from Kryptonite have done to her, Jodi stares angrily at her blender and throws it at the wall. Smashing one of the decorative plates on the kitchen wall in the process.
- Required Secondary Powers: Since Jodi needs to be able to drain fat from large animals and full-sized humans, the Kryptonite shakes give her the ability to unhinge her jaw and widen her mouth to impossible levels (like a lamprey eel or snake).
- Take Our Word for It: The deer that Jodi hit with her car and drained fat from, which Clark and Chloe investigate. The look on Clark's face and his remark about how it "looks like jerky" tells us everything we need to know.
- Villain of the Week: Jodi Melville, fat-sucking vampire.
- Weight Loss Horror: Jodi's rapid weight loss leads to her craving high-calorie foods nonstop, and she's eventually forced to turn to animals—including humans—to suck the fat from their bodies. It leaves her bully Dustin comatose and would have likely killed Pete and Clark if she hadn't stopped herself.
- Dustin's emaciated form after being attacked is another example of this trope: he has no fat on his body and he can barely wheeze out "Help me" before collapsing.
