Clark learns (or not) that he can be very persuasive (i.e. hypnotize people) when exposed to Kryptonite dust. My question is what kind of kryptonite dust is that?? It looked white to me. White kryptonite? Clear crystal kryptonite? Has he been exposed to that before? There's the green kind, and the red kind, and the blue kind.... hmmmm.
It's called Gemstone Kryptonite and it's unique to Smallville.
