its also possible that its an episode where Clark is without his powers, for some reason.
Again.
Scenes/cliches that need to not happen anymore on Smallville.
1) Clark tries to stop the villain of the week, usually about 15 minutes in to the episode, and gets thrown back through a wall or the ceiling in his barn. Villain escapes. (The best one was when Doomsday did it and he just happened to knock over a box with kryptonite in it!

)
2) Clark superspeeds in to a situation to rescue someone and runs straight in to a room full of kryptonite meaning he needs to be saved himself. ("Justice" is the best example, ruins an otherwise great episode)
3) Villain of the week is an ordinary human who happens to have some sort of kryptonite-related thing going on (like kryptonite counterfeit money or kryptonite jewelry).
4) Or - Villain of the week is no match for Clark but becomes aware of both his abilities and how to stop them (usually by overhearing Chloe talking about it) and leads Clark in to a trap.
5) Villain of the week is defeated 30 minutes in to the episode leaving us with a 15 minute long musical montage with various shots of Clark pining over Lana/Lois.
6) Not-Quite-a-Villain (i.e. a "hero" with a generally less well developed sense of morality) disagrees with Clark and uses kryptonite/magic on him to get their own way. See Queen, Oliver; Zatara, Zatanna.
7) Clark loses his powers and is, for some reason, turned in to a normal human. Important point here - Clark is not human. His ability to store energy from a yellow sun is a natural ability just like humans have the natural ability to breathe and eat food. If anything, he should keel over and die without it.
7a) Clark loses his powers and ACCEPTS the situation, ignoring all the good that he is now unable to do.
8) Character who doesn't know Clark's secret becomes suspicious only for Clark to be briefly exposed to kryptonite or lose his powers and then get beaten up by the villain of the week right in front of said character.
