Continuity mistake: At the end of the episode on 4/10/06, Billie realized that the trapped girl's cell phone was Chelsea's, and at the same time Bo went into the sewer and discovered that the girl was Chelsea. At the start of the episode on 4/11/06, Billie yelled down to Bo that the girl was Chelsea as soon as she realizes it, and Bo then continues into the sewer, already knowing that the girl is Chelsea before he reaches her.
Continuity mistake: On 9/7/04, Dr. Bhalla is surprised to hear that Rex is "not a wealthy DiMera after all," but rather a "blue collar Brady." In fact, Dr. Bhalla's response is, "I had no idea." But just a few scenes earlier, when Dr. Bhalla entered Rex's loft, he greeted him as "Rex Brady." If Dr. Bhalla didn't know about Rex's parentage, then he should have called him "Rex DiMera," the name Rex used when he was a student at Salem University.
Continuity mistake: On 5/26/05, Chloe was not seen for several scenes in the middle of the episode, while her bandages were changed. However, when we saw her again, a careful observation reveals that the bandages haven't been changed at all. A number of minute details remained the same, such as a slight gap in the gauze at the right corner of her mouth and a loose strip projecting from the wrapping at her left temple. If Chloe had received new bandages, there would have been visible differences in the appearance of the cloth.
Continuity mistake: On 12/7/04, Abby and Chelsea tried to sneak into Jennifer's house, because it was already after curfew. Jennifer caught them and sent them to Abby's room, but they sneaked out to go to a boy-girl sleepover. The same night continued to get later and later, but then on 12/20/04 Jennifer called Abby on her cell phone and told her to make sure to get home by her 8pm curfew so they could decorate the tree.
Continuity mistake: On 4/28/04, Mickey called Julie, "Julie Horton Williams." But that's not Julie's name. Her maiden name was Olsen, not Horton. Although she is a member of the Horton family, "Horton" has never been a part of her name.
Continuity mistake: On 9/17/04, when Sami, Lucas, and Will went to the Chinese restaurant, a pan of the room initially showed that Kate was sitting far away from them. Later, when Kate heard Sami speaking, she turned around to peer through the plants lining the ledge above her seat, and Sami was sitting right there, much closer than she had been before.
Continuity mistake: On 7/7/05, Mickey talks about how he, Rex, and Patrick may have made a mistake in going to the police station "tonight." However, both prior to and after that scene, it was full daylight not only in Salem, but even on the plane that was carrying Belle and her family back from Europe, where it would have been hours later than it was in Salem.
Continuity mistake: At the end of the episode on Friday, 3/11/05, Bo and Hope were in the elevator when Billie called out that the DNA results were ready. Bo had to use his body to block the elevator door from closing so he could go back out onto the hospital floor. At the beginning of the episode on Monday, 3/14/05, Bo and Hope were still waiting for the elevator to arrive when Billie called out to them.
Continuity mistake: At the end of the episode on 3/13/06, Lexie agreed to have sex with Tek in the small clearing where they were standing, while Sami was spying on them. Then, on the other side of the bushes where she was hiding, Carrie suddenly collapsed in pain. At the beginning of the episode on 3/14/06, Sami was still in the bushes and Carrie was still doubled over in pain as if no time had passed, but Lexie was at Marlena's penthouse and Tek was at the Brady Pub.
Continuity mistake: On 7/4/06, Kayla has a flashback to what she says is her and Steve's first Fourth of July with their daughter Stephanie. That would have been July 4, 1990. They talk about the various characters they're going to see at the barbecue later, including Jack. But Jack and the others they mention were actually stranded on a deserted island during the summer of 1990.
Continuity mistake: On 5/8/13, Kristen DiMera mentions that her wedding to John Black took place 15 years earlier. This is factually correct in terms of show history. However, it draws attention to the fact that EJ DiMera, the child born to Kristen's impostor around the time of the wedding, was heavily SORASed (Soap Opera Rapid Aging Syndrome) and is portrayed by a 34-year-old actor.
