:I'm having some difficulty taking seriously this discussion about each and every form that kryptonite takes in a single tv series, even one as long-running as Smallville. And I should point out that citing different episodes and then drawing conclusions/inferences/implications from the viewing of those episodes, without a single shred of reliable sourcing from a notable reference commenting about any of this is going to attract a lot of deletionist attention. I'm going to wait about a week, giving the main contributors to this series to come up with some sourcing that isn't directly lifted from the series (and therefore OR) before starting a fairly large trimming. It cannot remain in its current form. -
