Continuity: Throughout December, it was explicitly stated over and over again that Sheridan and Luis were getting married on the day after Christmas. But on 12/31/04, their wedding was still going on, yet it was New Year's Eve.

Plot hole: On 10/4/04, Paloma received a call on her cell phone from her Aunt Maria. But earlier in the year, the only way that Paloma and other people in Puerta Arena could communicate with people in Harmony was via a very low quality telephone land line. And even if one of the Cranes had given Paloma a cell phone when she arrived in Harmony, how would her Aunt Maria have the number?

Plot hole: When the doctor told Theresa that she was carrying twins, he told her that each baby had its own amniotic sac and that therefore they were fraternal. This was stated over and over again in the next few episodes. However, identical twins can also have separate amniotic sacs, as long as the egg divides early enough in the pregnancy. It is not uncommon.

Continuity: At the end of the 5/24/04 episode, Luis put Sheridan into the back seat of his car and drove off with her while she insisted that she didn't want to go. At the beginning of the 5/25/04 episode, Sheridan was sitting in the front, still insisting that Luis take her home. But how did she get into the front seat?

Continuity: In every single scene that Theresa appeared in for an entire week in October, 2003, some member of the hospital staff was telling her to leave the premises immediately. She was told "for the last time" at least six times, and Dr. Taylor said twice that he was going to call security. Yet Theresa stayed at the hospital without anybody actually doing anything about it, and she managed to exacerbate Gwen's condition three separate times.

Factual error: On 4/5/07, Chad had a flashback to when he met Vincent at a gay bar, over a year earlier. The song playing in the bar was Pink's "U + Ur Hand," which came from a CD that wasn't released until months after the scene took place. That particular song wasn't released as a single until about an additional year later.

Plot hole: When J.T. Cornell's dead body fell out of the wedding cake on 12/28/06, Rebecca fell all over him, lamenting loudly to everyone about how much she loved him, how much he meant to her, and how amazing the sex was. (She was really just looking for his flash drive.) However, Rebecca and Gwen had spent the entire fall trying to prevent Ethan from catching Rebecca and J.T. together, because Ethan was convinced that if Rebecca and J.T. knew each other, then it would mean Rebecca and Gwen were lying about the tabloid, which they were. So Rebecca's behavior should have been a huge tipoff to Ethan, but instead he had no reaction at all to this.

Continuity: Early in 2006, when she was planning to become a nun, Whitney whipped herself on the back to punish herself for her sins, injuring herself badly. In December of that year, she got married and wore a gown that revealed much of her back, but there were no scars at all.

Continuity: On 7/19/06, Tabitha told Endora that Siren's aphrodesiac stew was more powerful than her own lust potion. On 7/21/06, Tabitha told Siren that the lust potion was ten times as powerful as the stew.

Factual error: In the spring of 2006, Whitney traveled from Harmony to Rome, and we are left to assume that she flew. After Whitney had arrived in Rome, Chad and Simone found out and went to Rome to find her. Paloma and Jessica accompanied Simone. After Paloma arrived in Rome and got into some trouble, Theresa and Ethan found out about it and went to Rome as well. So there were three consecutive trips from Harmony to Rome, and they all happened during the same night; Whitney left after dark, and Theresa and Ethan arrived in Rome the following morning. But each flight to Rome should take six hours, and there is a six hour time difference, which adds up to a full twenty-four hours. So nobody who left Harmony at night could have arrived in Rome before morning. And Theresa and Ethan should have arrived in Rome after dark on the second day, not first thing in the morning.

Factual error: On 5/18/06, it was simultaneously breakfast time in Rome, Italy, and in Harmony, Maine. But since Rome time is six hours later than Harmony time, this is impossible. Breakfast time in Harmony is lunch time in Rome, and breakfast time in Rome is the middle of the night in Harmony.

Plot hole: In April of 2006, Whitney disappeared from the convent very late at night. Later that same night, it was discovered that she was in Rome. But we never saw her get on a plane - only walking through catacombs with the monk the whole time - and even if she did get on a plane, there hadn't been nearly enough time for her to get to Rome.

Continuity: On 3/10/06, Endora sneezed and Tabitha said "Bless you." Since Tabitha is a witch, and holy water and crosses burn her skin, and she can't enter a church, and any time Endora used to mention angels it caused Tabitha's entire house to shake, it should definitely be impossible for Tabitha to say "Bless you." The little girl sneezing was probably unscripted, and "Bless you" was the natural response of actress Juliet Mills.

Continuity: On 9/15/05, Ethan referred to Grace Nancier's plea offer as three fifteen year sentences, "served concurrently." But the offer was for sentences served consecutively, which is a big difference.

Continuity: Several times during the tsunamis, in the week of 8/1/05, Sam Bennett's shirt would switch between being yellow to a light orange from shot to shot. The orange shirt was distinctly darker than the yellow one, even when both were soaking wet. Actor James Hyde was wearing the yellow shirt, but his stunt double had the orange one.

Factual error: On 7/29/05, the men at the Tsunami Warning Center talked about the tsunami that was heading towards Harmony, and then the scene shifted to a giant wave. However, the shot was of a large, cresting ocean surface wave. Tsunamis are very different from surface waves in many ways, the most notable of which is that a tsunami at sea is only a few feet tall at most. Even when it approaches land it behaves like a violently oncoming tide, not a cresting wave.

Other: On 2/18/05, during Beth's "Law & Order" fantasy, the caption gives the date as "Febuary 18" instead of February.

Plot hole: Martin and Katherine have been living under the assumed names of Bob and Ellen Wheeler. Despite forming very close bonds with several characters prior to falling out of favor with the revelation of Martin's real identity, they were almost never referred to as "Bob and Ellen." Almost everybody called them "Mr. and Mrs. Wheeler" at all times, even though the entire rest of the town is on a first name basis, even with the wealthy and powerful Alistair Crane. Martin and Katherine themselves called everyone else by their first names, and such forms of address are almost always reciprocal among adults.

Continuity: On March 10 and 11, 2004, a group of characters sings an original song, "Shugga Shugga Shugga," on the stage of the Blue Note. The song plays as background through numerous scenes, and lasts for more than twenty minutes. But the same two or three verses were simply played over and over again. In fact, the song is available on the show's website, and is not even five minutes long.

Revealing: On 12/24/03 and 12/25/03, Sheridan is supposed to be breastfeeding baby Martin. But Sheridan's shirt is barely unbuttoned, and pulled aside only marginally (and mostly from the opposite side of where the baby is). For his part, the baby is not even turned towards Sheridan's body. So, the way the scenes are shot, there's no way he could be nursing.
