Plot hole: On 4/5/05, Rex surprises Mimi on the roof with a romantic dinner. He also plays Jesse McCartney's "Beautiful Soul," which Mimi identifies as "their song." But Rex and Mimi started to get together as a couple about two full years ago. Why would "their song" be something that was released in the last two months?
Continuity mistake: On 3/16/04, in John's hypnosis-induced vision, he reacted violently against the idea that Marlena might be the "Salem Slasher." But the serial killer has always been called either the "Salem Stalker" or just the "Salem Serial Killer." The Salem Slasher was actually the name used when Andre DiMera went on a killing spree in 1984.
Factual error: On the 11/11/03 episode, Phillip is on the computer at the police station, searching to see if the serial numbers of Rex's mask matches the killer's mask. Problem is, he should be able to tell right away that they aren't the same masks. They have a video image of the killer killing Maggie and his/her mask has three holes above the eyes and eight holes near the mouth. Rex's mask only has two holes above the eyes and six holes by the mouth.
Continuity mistake: On 2/27/04, Julie made a phone call and told the person on the other end that Doug believed he knew the serial killer's identity, and only then did she directly address the person as Marlena. On 3/1/04, when Marlena flashed back to the conversation, Julie immediately greeted her by name before explaining Doug's situation.
Continuity mistake: On 12/31/07, E. J. mentioned how he had been struck in the head "the other night." The attack, which had been shown on 12/27/07, was one of the first things to happen that day, occuring in the morning, not at night. It was also the same day (for the characters) as when E. J. was speaking of it.
Plot hole: On 1/25/05, Belle asks the jewelry store proprietor to recommend a medal to give to Philip, who is going to war. The lady suggests that Belle buy the same medal she had given her own grandson when he went to war. But on 1/26/05, when Belle gave the medal to Philip, she told him that it was the same as the medal that her grandmother had given to her grandfather when he went off to fight in WWII. If Belle knew about a medal that her grandparents had once exchanged, why didn't she just ask the lady for that particular medal?
Plot hole: On the 11/17/03 episode, it was stated that the sudden darkness on 11/14/03 was the result of an eclipse. But that doesn't make sense at all. The characters were very surprised by the event. However, the times and locations of eclipses are always well known to astronomers. When one is going to happen, close to everyone in the affected area is aware of it. If an eclipse really happened "out of the blue" without anyone expecting it, it would be instantaneously newsworthy on a global level. The explanation that because of the serial killer being featured in all the headlines that they had not noticed the information about the eclipse makes no sense, as the same people who normally know about impending eclipses would have known about this one.
Continuity mistake: On 10/9/03, Marlena sees the blood-red moon and says that she does not believe in signs or omens because she is a psychiatrist. Marlena was possessed by the Devil in 1995, so it doesn't make sense for her not to believe in mystical things, woman of science or not.
Continuity mistake: In the premiere episode, which aired on November 8, 1965, Alice mentioned an absent son, saying, "Poor Dan married Kitty down at city hall just before he was shipped overseas." Two years later, Alice's son was found alive and his wife, with whom he reunited, was still named Kitty, but the man's name had changed to Tom Horton, Jr.
Continuity mistake: On 11/10/04, Bonnie and Mickey's wedding ceremony began. The justice of the peace called Bonnie "Maureen Bonnie Lockhart." When Bonnie was introduced to the show she talked about how her ex-husband demeaned her by insisting on calling her by her middle name, Maureen, so her name should be Bonnie Maureen Lockhart.
Plot hole: On 7/7/05, Lucas told Sami that Will had called him from summer camp to say he was having a good time but misses Sami. However, just a few episodes earlier, when it was already the same day, Sami was making an American flag dessert that she said was for Lucas and Will. So why wasn't Sami surprised to hear that Will is away from home?
Continuity mistake: At the end of the 3/1/04 episode, Mimi was talking to her mother Bonnie on the phone. Bonnie told Mimi that she needed her to come home to help her right away because her son Patrick was back in town. Mimi asked why her mother needed her help with that. We didn't hear Bonnie's end of that conversation, but whatever she told Mimi alarmed her enough to cut her romantic evening with Rex short. At the beginning of the 3/2/04 episode, Mimi was back at her mother's house, but was still asking to know why it was so important for her to be home, as if Bonnie hadn't told her over the phone.
Plot hole: On 12/16/03, Roman and Kate find out that Sami tried to frame Kate for the recent murders, and Kate asks Roman if the fact that Sami would frame her for murder might suggest that she could also be capable of actually committing murder. There are two very strange things about these scenes. The first is that Sami never brings up the fact that Kate framed her for murder years ago, which actually put Sami on death row in 1999. The second is that Sami's attempt to frame Kate seems to be the closest thing to murder Kate can think of to incriminate Sami, even though Sami actually shot a man (in the testicles, no less) in 1994.
Continuity mistake: On 11/30/05, Mimi's cell phone rang. Before answering the call, Mimi looked at the display and said to Shawn, "It's Belle." After she hit the button, the shot changed to Belle at the hospital. Belle was holding a land-line phone at the hospital. So how could Mimi's caller ID have possibly known that Belle was making the call? It should have said that the call was from University Hospital.
Plot hole: In 1998, Billie gave birth to a baby, Georgia, that she believed to be stillborn. When she and Bo found out in 2004 that Georgia was really alive, Billie lamented having missed fifteen years of her daughter's life, and they talked about how their daughter would now be a teenager. But Georgia should only be six years old.
