Plot hole: Chloe writes her phone number on Sean's hand. It disappears when we see him struggling against the ice of the lake, then reappears in the scene where he is calling old girlfriends. And how exactly would pen ink survive several hours submerged in water and then another eight hours of normal activity without becoming blurred?

Audio problem: When Sean flags down Whitney's truck, we hear his brakes squeal as he slams on the pedal. A few quick cuts later we see him do the same thing, apparently for the first time.

Continuity: When Sean emerges from the lake and goes to the campfire, his clothes are completely dry despite the fact that he was totally underwater for hours.

Continuity: When Sean is in the nurses office, having his temperature taken, the light on his left side is on. After the nurse wants to retake the temperature the light is now off.

Continuity: As Sean sucks electricity at the power station, his arms are bent in the first shot and fully extended in the next.

Continuity: When Henry falls into the pond, the first time, there are several small pylons connected by a chain when the camera is on the walkway. When the camera is in the water, showing Henry as he hits the water, neither the pylons or the chain is visible. There is just an open space where the chair falls over.

Continuity: As Harry goes into the pond the second time the pylons are connected now with yellow crime scene tape when the camera is out over the water looking at Harry on the walkway. As the camera is in the water, watching Harry fall in, the pylons are gone, even though they should be in the shot, and are connected by a wire instead of crime scene tape.

Continuity: In the closeup when Zoe is introduced, the button just above her apron is buttoned. In the next shot of her walking through the cafe, it is unbuttoned.

Plot hole: Chloe hands Clark a newspaper with the list of jury members from Harry Volk's trial. As he reads the list he says "Rudolph Gage, Rita Garfield". After Clark realizes that his grandfather, Hiram Kent, is on the jury he hands the paper to Lana. A shot of the newspaper has the jury members listed as Randolph Gage, and Eve Garfield. Even young Harry calls her Eve when confronting Zoe at The Beanery.

Continuity: As Chloe enters Clark's house, Clark is putting a blue shirt on. When she first starts to talk to Clark, with the camera on Clark's right, he is buttoning the top button. When the shot switches to behind Chloe, the upper part of his shirt is open.

Visible crew/equipment: When Clark and Chloe begin their investigation on the deer, when Clark pulls the blinds, you can see the shadow of the crew equipment on the left side of the blinds.

Continuity: When Jodie hits the deer her vehicle spins out. As it is spinning the headlights are not projecting any kind of visible beam. After the car stops, and she is facing the deer she hit, the headlight is now projecting a very bright beam to illuminate the deer on the road.

Audio problem: Clark listens to his father and Earl talking in the hospital through the visitor window. The sound is the same volume and quality as when Earl was using the microphone, which he is not using now. Even if Clark used super-hearing to eavesdrop, it wouldn't sound the same as the microphone.

Audio problem: After he breaks the methane valve, Earl runs to the security camera and whispers, "You see what you made me do?" His whisper is heard at the proper volume by the Luthors watching the camera, but the speakerphone is on the desk ten feet behind Earl, making this impossible. Most surveillance cameras don't have microphones.

Revealing: In the early scene with the baby, there are a few overhead shots of the parents and child. It is clear that in these shots a fake baby was used - he is completely motionless, even though he was moving arms and legs before and after and is crying.

Continuity: For several shots during the early scene with the baby in the crib, the blanket changes back and forth from tucked up to the chin, up to the shoulders, and up to the stomach in different angles.

Continuity: While Earl is in the hospital bed, his grip on the microphone to the waiting room changes from up to down and back.

Audio problem: When Pete is stammering to the Kents about Clark returning to the plant, his lips don't match the sound, especially toward the end.

Audio problem: After Clark's parents come home, after their anniversary dinner, Jonathan and Clark go to see Earl in the hospital. As the Doctor says "It looks like he's got some sort of mineral poisoning, but its not from any mineral I've seen before." For the first few words of that line her mouth does not match up to what is being said but the dialogue, and her mouth slowly come together at the end of the line.

Continuity: After Clark cleans up the house, the amount and kinds of fruit in the basket on the table changes between the pan shot to his parents and the shot of the three of them at the table.
