Corrected entry: Tina Greer disguised as Whitney walks down the hallway dressed in marine corps dress blues. His rank was a private first class, yet he had a blood stripe going down his pant legs. You do not receive the blood stripe until you reach corporal. Also the medals were wrong and some missing (i.e. combat action). The marine that comes to the house later and is killed by Tina Greer, had medals that were wrong as well.
Corrected entry: Chrissy is the leader of Spirit Week and is trying to organise it. We see her kiss her boyfriend Troy, and suck the life out of him a few days before Spirit Week. However, Chloe pulls up the file on Troy, and it says his date of death is June 20, 2002. This is highly unlikely, as Spirit Week is put on in the days leading up to homecoming, and homecoming is usually in late September or October.
Corrected entry: Clark is supposed to hide his powers from everyone. When the other swimmer in the final race starts to drown Clark uses his super speed to get him off of the bottom of the pool. Everyone who was in the pool area had their eyes on the drowning kid so somebody should have seen Clark just appear at his side.
Corrected entry: Clark brings Pete along when he retrieves the DNA sample taken from him so that he can use his DNA to replace his. However, Pete is African American in origin and it would show in his DNA when they try to analyze it. Using Pete as a substitute DNA donor would cause further alarm because Clark is white but the DNA sample which was supposedly taken from him would result in someone of African American in origin.
