Revealing: Once Victoria has drawn her bath, we see her get in, and then lean back into the water. However she is already wet on her chest and her hair is damp already. This is probably due due to previous takes of the same scene.

Continuity: At the beginning, when Seth picks up the barbell to beat Troy with, Troy is at the end of the locker room with the showers. As Pete and Clark show up, Troy is at the other end of the locker room.

Plot hole: Seth is using a cream made of green (i.e., kryptonite) roses to make himself invisible. At the beginning of the episode, Clark is in the locker room and feels ill from the kryptonite rose cream that Seth is wearing as he beats up the kid who picked on Amy. For the rest of the episode Clark does not feel the effects even though Seth is close enough to him at least two other times in the show. Once after Seth trashes Victoria's room and runs past Lex and Clark and again when Seth tries to drown Victoria in the tub.

Continuity: When Clark and Lana almost kiss, shots on him show him turning to his left, but shots on her show him turning to his right.

Continuity: At the coffee shop when Chloe volunteers for blood donation, there is a shot on Clark as Lana walks away where we see Chloe's head turn. When the camera comes back to her she is sitting exactly as before.

Continuity: When Amy is introduced, she is writing about two lines down from the top of the page in her journal. After Troy snatches it, the writing runs about halfway down the page.

Continuity: As Victoria is being drowned in the bathtub, she appears very deep in underwater shots and only a few inches down in overhead shots.

Continuity: As Clark first walks up to Whitney in study hall, Clark's arm changes from bent to straight at his side.

Continuity: When Jonathan is sitting down, before he tells Clark that he can't always be honest, in the shot from the other side of the table Jonathan is holding a book in his right hand as he is sitting down. When the shot switches to Clark's right, Jonathan is still starting to sit but now the book is in his left hand.

Continuity: After Clark and Chloe make their plans for investigating the invisible person, Clark turns away to leave twice: once with the camera on him and once with the camera on Chloe.

Plot hole: Clark realizes that Amy stole Lex's watch when he sees her wearing it. He and Lex then search Amy's room with her mother and find the watch. Amy wears the watch as a token of her obsession and would not take it off lightly, even if she had returned home and left again.
