When Johnathan and Clark are loading the truck you can see the truck move with the weight of the bags Johnathan adds but not the ones Clark throws inside.
Spelling mistake - on an Eddie Cole ad that reporter gives to Lex is spelled "NOTHING TO LARGE, NOTHING TO SMALL" when it should probably be "NOTHING TOO LARGE, NOTHING TOO SMALL".
Chloe is strangely not curious as to how Clark rescued her from being buried alive, as is Lana, as neither of them are yet aware of his powers. He used his strength to pull her out instead of digging her out by hand, which would have taken hours for a normal person to accomplish, yet neither of them seem are curious as to how he did it so fast by himself.
Chloe is strangely unhurt when Clark violently rips the metal coffin she is in out of the ground, as the force of the upward movement should have caused her to be injured by being thrown around the inside of the very solid interior. This could be attributed to Clark's often hinted-at, but never stated ability to partially extend his invulnerability to the objects and people he touches. In the comics, this ability is referred to as Tactile-Telekinesis.
