Smallville

When Sheriff Ethan runs to get Clark out of the jail area when the fire has started, he unlocks the door, in the second or so it takes the camera to follow him, the wall the gate locks to is clearly visible... with no lock plate attached to it.

Toward the end, Clark prevents Desiree's escape by using his heat vision on the door handle. Even if she didn't know how hot it was upon sight, there's no way Desiree should have held it as long as she did. Her natural autoreflexive action should have been much faster against something bearing such high degrees of heat.

Jonathan tells Martha they don't have air conditioning because of the electric bill. However, in Drone, Clark says Martha is addicted to the Discovery Channel. The Kents can't afford an air conditioner but they have cable TV? (editor's note: of course, they may have less money now than they did then...)

Why does Clark use his heat vision to stop the bullet at the end of the episode? Wasn't that just a tad risky, seeing as how he had just acquired that ability and really had little to no experience using it? A great time to experiment - Lex could have been killed! A simple superspeed run-and-block from Clark would have sufficed. How did he get so good (amazing split-second, pinpoint precision heat vision) so fast, anyway?

When Clark heats up the popcorns with his eyes, it looks like Clark wanted the heat-beams to come out for a longer duration than the special-effect crew agreed on.

When Clark put the scarecrow in the ground, look at Jonathan's belt. Isn't that belt just a little too nice to wear while working on a farm?

Why is Clark sweating during a heat stroke of possibly 100 degrees but when his car explodes he says he didn't even feel the flames? (some thought it might be tied in to the emergence of his heat vision powers.)

Does Martha have a bakery somewhere on the farm, because there's no way she could bake a six-tiered cake in less than a day without several ovens, particularly the size that cake was). Also, Martha looked amazed when Clark announced that Lex was getting married. Wouldn't having baked the cake herself tipped her off? At the point when Clark was telling her, she should have been either putting the finishing touches on it, or at the wedding site assembling it. Also, the timing was: Lex gave Clark the invite at school, when Desiree was teaching, saying the wedding was that night. Then Clark goes home, tells parents as Desiree has Lex rip up pre-nup, and the wedding that early evening, when Clark says his mother put finishing touches on cake 2 hours ago (when Martha appeared stunned at Clark's news RE: Lex's impending wedding). (editor's note: it's possible Martha may have just decorated the cake, not baked it, but even so the whole sequence seems badly timed)

Nearly three months have passed since the tornado struck and the Kents don't seem to think twice about where the spaceship ended up after the storm. Odd, considering they were so uptight about it when it was hidden in their storm cellar.

Why does Desiree have to work on her wedding day? You'd think she could take a day off to get ready, what with marrying the richest man in town in an incredibly fancy wedding ceremony.

It's one of those things you see in a lot of shows and movies: Desiree frames Clark but has no (apparent) idea where he is at the time the crime is being committed. What if he's sitting at home watching TV in front of Ma Kent's knitting bee? Or out at the Talon with friends? As is almost always the case, conveniently Clark has no alibi.

Now Jonathan strolls into Lex's manor pool. Lex really needs to get some security guards.

Why don't the Kents alibi Clark? Okay, they probably wouldn't be believed but they don't even try. Are they really so honest that despite the fact they're sure that Clark didn't commit the crime and that he's being set up, they wouldn't lie to protect him?

So what did Lex's dad say about Lex ripping up the prenuptial agreement? Nothing?
