When Clark steps out of the shower his hair is dripping wet in the next shot it's considerably dryer.
Lex continually says his Jet was at 20,000 feet when the door got torn off, but when he is talking with he NTSB agent the screen in the background says the Jet was at around 45,000 feet.
In the previous episode "Crusade" Chloe's grave was on the right side of her father's. When Lois digs out her coffin in this episode, the grave is on the left side.
When Lois is running from the helicopter, a rainbow is seen on the horizon. This is impossible as in the show, it had not rained at all that day.
When Lois is digging up Chloe's grave, no burial vault is seen. All caskets are placed in a burial vault to prevent the ground from caving in around the casket.
There is an editing error when Clark is talking to Lex in the home that Chloe was taken from. A shot on Tom Welling while talking, shows the side of Michael Rosenbaums' face who is also clearly talking. In the final cut of the episode Michael's mouth is moving but no words are heard.
