Sunshine and Frosty Swirl - S7-E2
Continuity mistake: When Wayne Randall is eating ice cream, the size/amount of ice cream on the cone changes as the camera pans back and forth between characters.
Continuity mistake: Near the beginning of episode 3, season 7, Dexter is attempting to take a mouth swab of a criminal in the interview room. When he first sits to request a swab from the man he is shown putting on forensic gloves. When the camera pans to him a second time to attempt taking a swab he no longer has forensic gloves on. As the man resists opening his mouth for a swab check Dexter is wearing forensics gloves again.
Factual error: In The Beginning while Dexter is on his boat in Miami, you suddenly see mountains in the background, of which there are none in Miami. Also the palms are too high, indicating they are from California. And the worst setting mistake is the Florida tags in front of the cars. Only commercial vehicles have front tags.
Continuity mistake: When Hannah calls Dexter at the bus crime scene, Dexter answers the phone normally but then in the next cut, the phone is upside down. (00:23:25)
Do You See What I See? - S7-E11
Continuity mistake: Deb's daily drive is an E46 '03-'06 BMW 3 series. In this episode she is in a car accident and when Dexter shows up at the salvage yard to check the vehicle he is led to an E36 '95-'99 3 series. (00:18:45 - 00:36:25)
Deliberate mistake: Season eight begins roughly 6 months after the end of season seven. However, at the end of season seven, Harrison is around 3 years old, and season eight has aged him up at least two years.
Continuity mistake: In the shot where Angel gives Dexter a gift from the recently deceased Maria's office, we see Masuka through the window in front of Dexter. Masuka then enters Dexter's office, showing Masuka in two places at once for at least two seconds. (00:30:55)
Suggested correction: That's not Masuka we see in the window. Not only is the person seen through the window wearing a different shirt, he's not bald like Masuka.
Continuity mistake: Quinn brings Deb into the interrogation room and puts his coffee cup down about 6-8 inches from the end of the table. He then moves his chair and begins to talk to Deb without touching the coffee. In the next several shots the cup has moved to the middle of the desk, and the amount of steam rising from the cup keeps increasing as it sits there.
Scar Tissue - S8-E4
Continuity mistake: When Debra is talking to Jacob Elway, a piece of salad appears on her fork and disappears the next second. (00:31:55)
Revealing mistake: When Dexter enters his apartment and finds Zach dead in the chair, you can see Zach's chest moving, showing he's breathing. (00:49:45)
Make Your Own Kind of Music - S8-E9
Continuity mistake: Scene with Deb and Joey having lunch. Their water glasses switch between having ice and lemon wedges, to having no ice and a lemon slice floating at the top. (00:20:15)
Continuity mistake: In Season 3, Episode 2 during a conversation with Miguel's wife Sylvia, (Syl), and Rita in a kitchen, Syl says that they don't have any children after trying. In this episode, Syl is trying to help Dexter sell his condo and says that she downsized and focused more on "the kids."
Suggested correction: She could be easily saying that for the kids, as in those that they are trying to make happen, as a potential space for them if they get lucky and become pregnant.
Other mistake: When Deb is dropping Hannah off at the hotel, after she pulls up to the entrance, you can hear her car idling while she and Hannah have a brief chat. When she pulls away after Hannah exits, she starts her engine.
Remember the Monsters? - S8-E12
Plot hole: In order to elude Elway at the airport, Dexter fills a backpack with random items and leaves it unattended under a seat, and then tells a desk clerk that he saw Elway deliberately put the backpack there and walk away, which leads to security detaining Elway and the airport being evacuated. Airports have security cameras everywhere, so security would have reviewed the footage and seen Dexter was the one who placed the bag there. They then would have gone through all security footage since he entered the airport in order to deduce his identity and then located and arrested him.
Remember the Monsters? - S8-E12
Plot hole: A couple episodes prior, Deputy Marshal Clayton stated that he shared Hannah's picture everywhere after receiving a tip that she may be in Miami. In the same episode, Hannah was spotted at a hospital and Clayton was called in about it. This should have only increased public awareness concerning her, but at the beginning of this episode, she somehow made it through airport security and all the way to her gate before spotting Elway and hiding from him in the ladies room.
Remember the Monsters? - S8-E12
Revealing mistake: In the flashback scenes when Dexter and Deb are shown holding baby Harrison in the newborn room, you can tell they are just holding a dummy in the wide shots because the baby never moves a muscle.
