Revealing: While there was a close up on Clark while he was asleep, you could see a small cut right above his eye, which is impossible if he can't be hurt.

Revealing: At the beginning of this episode Lana is supposedly naked. However, when she dives off of the pier, she is wearing a pair of red shorts.

Continuity: When Lana undresses before jumping into the lake, she kicks all her clothes right beside Clark's feet. But in the shot where she dives off the end of the pier, all of the clothes are piled well away from Clark.

Plot hole: In this episode Clark keeps having dreams of this girl who moved in Lana's old house, and is in a coma. In one of the dream sequences Clark says he doesn't have powers in the dreams. Yet in a previous dream he's with Lex at his mansion, and Lex takes a Japanese Katana and attacks Clark with it, but Clark blocks the sword with his arm and the sword blade shatters. If he doesn't have any powers in the dreams then shouldn't he have been hurt?

Continuity: When Clark goes to give the flowers to Sarah, her uncle answers the door. The first shot is of the uncle through a flyscreen door, which he opens. We then see a shot of Clark outside the door, and then the uncle opens the flyscreen door a second time.

Revealing: When Nicholas throws the lighter it is supposed to be lit so that it will light the gas and kill Lana but as it flips through the air, before Clark grabs it, the lighter has no flame at all.

Revealing: Lana and Clark are supposed to be skinny dipping at Crater Lake. When Clark pops up out of the water and goes "boo" to Lana she spins around and splashes Clark for making her worry. As she starts to splash Clark her body comes out of the water far enough to see she is wearing a tan tube top instead of actually skinny dipping.

Continuity: At the beginning when Clark and Lana are on the small pier by the lake, it alternates from sunny to shady between shots during the scene.
