Other mistake: When Billie visited Georgia's grave in Salem, she acted as if the baby was buried there, yet, Billie should know that the coffin buried is just a bunch of rocks and the real Georgia is buried where Earl, Wayne, and their mother live by the bayou. Billie lied to Bo about Hope being the cause of their baby's death and buried the rocks in the coffin to make it look like the baby had died after her fight with Hope, rather than before.
Other mistake: On 9/26/03, there was a quick montage of all the suspects in Abe's shooting superimposed on a shot of the comatose Commander Carver. It had been well established that the seven suspects were Kate, Lucas, Sami, Tony, Rex, Victor, and Nicole. However, Lucas was missing from the montage.
Other mistake: In the episode airing 10/18/05, Roman gets a cell phone call while in Alice's bar. The phone call is from Kate, informing him that John is about to storm the penthouse. During the phone call, Roman only says, "What the hell happened?" and "I'll get over to the penthouse as soon as I can." He proceeds to tell Bonnie and Lucas that he has to go and he'll be back, and nothing more. But later on in the bar, Sami asks where Roman went, and somehow, Lucas seems to be able to tell her that Roman went to the penthouse because of "Something about John." How did Lucas know that phone call was regarding John when Roman never said it for him to hear?
Other mistake: On the end of the 3/15 show, Jack is outside searching for Jen and then the fake Jen comes out of the house and tosses her hair to prove that she is the real Jen. However, Jack saw the real Jen before and she was wearing a black outfit, while fake Jen is in purple. He should have known that the Jen that comes out isn't the real Jen.
