Plot hole: On 4/16/04 and 4/19/04, John told Marlena that he had an idea that could prove Marlena's innocence, but could also potentially be fatal. Then, on 4/20/04, John acted surprised and upset when he learned that Father Jansen's possession test could have killed Marlena. But John was previously a priest - he even exorcised Marlena when she was possessed in 1995 - and definitely seemed to know that the procedure could be deadly, so his shocked disposition makes no sense.

Plot hole: On 7/8/04, Belle listened to her answering machine messages, hoping that Shawn may have called her. Her outgoing message was, "This is Belle. You know what to do. If this is Shawn, please call me." That doesn't make any sense. If Shawn is hearing that message, then he has indeed called her and doesn't need to be told to do so. And if he doesn't call, he will never hear the message asking him to call. Submitted by DavidK93

Plot hole: In January of 2005, John became a drug addict and was confronted by Nicole, Brady, and Kate. However, John was exhibiting all of the characteristic behaviors of drug addiction (lying, stealing, denying the need for help) as well as total chemical dependence, later on the same day that he first stole and injected painkillers. No addiction could progress that quickly. Submitted by DavidK93

Plot hole: On 11/20/03, the killer sends a full-color video image of Caroline to Bo's PDA. The PDA has a standard LCD display, and there's no way that any amount of "hacking" could possibly cause such an image to appear on that screen. Submitted by DavidK93

Plot hole: On 12/08/03, Belle and Shawn talk on the phone, and Belle briefly mentions something about how much she's enjoying Paris. But Belle was sent to Milan to keep her safe from the killer, and Jan also said that she had seen Belle while she was in Milan herself. Nobody ever said anything about her going to Paris.
