Plot hole: It's revealed at the end of the episode that the reason Tommie was sleep walking was because he was so nervous about the 5th grade test. However, he was sleep walking before news about it was given (ie: The beginning of the episode).
Plot hole: At The Beginning Sam stated that the missing teacher comes to work by subway every day. But in the flashback of his conversation with the drug dealer, he's about to get into his car. (00:13:00)
Plot hole: Didn't Dexter ever notice the giant fire pit in the ant farm?
Suggested correction: This is more of a question than a mistake. (To be fair, I don't think questions were a feature yet back when this was posted.) No, he didn't. He only noticed the fire pit (and the colosseum) when he was inside the ant farm. It most likely just wasn't visible to him from the outside, or it was too small for him to see it.
Only the Bad Come to Sonora - S4-E3
Plot hole: Manolito trades clothes with the poor peon he meets on the road. But at the end of the episode, he has the same clothes that he gave away earlier (his usual outfit) back on again.
Plot hole: In the very last episode of the show, "George Decides To Sta-Local Where It's Familiar", Angie mentions that they conceived their "kids" there, referring to both Carmen and Max. However, the season four episode "George Takes a Stroll Down Memory Pain" showed flashbacks where Angie and George were living with Benny, and Angie was far along in her pregnancy with Carmen. Only Max could have been conceived in the house that they are currently living in. I want to add that in the episode 'Valentine Massacre', George says"What about the first time we made love. What were the odds in Vegas!?!"
Plot hole: The ages of the children on the show are really inconsistent. When the show starts in 50 BC, Octavian is around 12, Lucius is an infant and Vorena the Younger is at least 8 (given that she must have been concieved before Vorenus left for Gaul). Three years later Caesarion was born. When Simon Woods takes over the role of Octavian, Octavian is around 19, as stated on the show. Lucius should be seven but looks like he's four and Vorena should be fifteen but still looks eight. Episode 9 of season two takes place in 32 BC, 18 years after the first episode. Octavian might very well be 30, but Lucius (who would be 18) is around seven, Vorena (who would be 26) is a pre-teen and Caesarion (who would be 15) is around eight. Even if the events were moved up so that episode 9 is actually set earlier, the ages of the children still don't match when compared to how much the other characters have aged.
April Fools - S5-E18
Plot hole: As Mama tells Iola about the April Fools' jokes the family has played on her over the years, Iola expresses surprise. Considering Iola has been Mama's friend for years and is constantly at the Harper house, it seems impossible that Iola had never heard of any of the April Fools' pranks.
Wuffenloaf - S3-E1
Plot hole: When Abby and Eric return the night vision goggles, Abby asks if they should put them back exactly where they were and Eric says he didn't remember where they went but luckily he "took a picture" of how it looked before. How could this be possible if Abby purposely excluded him when she collected those goggles from Lisa?
You Gotta Not Fight for Your Right to Party - S2-E6
Plot hole: When Miley (as Hannah) gets stuck in the truck while trying to escape, she tells Jackson that her "belt's caught". But, when Jackson rescues her, it is visible that she is wearing no belt.
Slave Island - S1-E7
Plot hole: After Storm's attempt to escape the Genoshan prison is thwarted, she ends up in the ocean right at the shoreline of the beach, where she is captured by a Sentinel. Aside from the fact that it makes no sense for a Sentinel to be hiding in the ocean in the event that a mutant tries to escape the prison, there is absolutely no way that a two-story tall robot could hide in the ocean right by the beach, as the water would be way too shallow. You can even see that the water level only goes up to the Sentinel's ankle area when it is standing upright in the ocean. (00:03:15)
Suggested correction: Perception. (1) The Sentinel isn't as close as it appears. If it were close, then she would have been caught in its waves as it emerges. Also, she would be looking only at its chest circle. It's several yards away. (2) She washes ashore. She fell from the sky. She couldn't have fallen from that great height into shallow water without hitting bottom. (3) It's also a two-story tall robot. Its weight would sink it into the sand. So it could have very well been down that deep.
Sentinel never sank into sand in other episodes.
Well, it's shown here.
Plot hole: In the episode "Where's the Wizard?", when Pim gets the Wizard from Lil' Danny, she holds it in her hand. When Lil' Danny steals it, he takes it out of Pim's backpack, meaning it must be Pim's Wizard. But when Phil points it out, she says it's hers. This could be a character mistake, but if it was Phil's Wizard, they would not be able to track the one Hackett had, because inputting the signal of Phil's Wizard would do nothing.
The New Era - S2-E4
Plot hole: Early in the episode, Alex tells Seth that the night of the Killers concert is her night off. (She works at The Bait Shop, the concert venue.) At the end of the episode, Alex is paying The Killers, as if she were the manager on duty.
Plot hole: Vaughan discovers Lauren is a mole when he goes through her briefcase and discovers the wig, gun and fake passport she used in Germany a few hours before - surely even the worst secret agent in the world would have enough sense to get rid of such incriminating evidence as soon as possible, and not carry it back to the USA (sneaking it onto a plane, presumably) and leaving it in the room where the man you're lying to sleeps. Lauren is a highly skilled agent, if the Covenant selected her for a mission this important, so it's out of character (without an explanation) for her to be so sloppy.
Plot hole: In the episode "10,000 Steps," the parents from Amy's case say they adopted their first son Daniel when he was 3 because they thought they couldn't have biological children. Howeve,r the birth of their other son Seth proved that theory wrong. But Daniel is 13 and Seth is 12, so when Daniel was 3, Seth would have been 2 already.
Chain Gang - S6-E3
Plot hole: When all the gang including Arnie leave the flat to go to the restaurant to meet Mr Stavros, Rodney decides to stay at the flat and wait for Cassandra to phone him. The next scene shows the gang all watching Arnie in the restaurant waiting for Mr Stavros to arrive. Rodney is sat in the van with Uncle Albert but Rodney decided to stay at the flat so there was no way of him being there.
Plot hole: In order for the show to be starting on "Day 1,412" as counted back from Cooper's eventual high school graduation, it would have to be a mere 49 days after his graduation from the eighth grade. (4*365 = 1460 + 1 for leap year) So it should be the middle of summer, but instead the school year seems to be in full swing. For example, it's already the end of Natalie's soccer season.
Plot hole: Tahnee was sent to boarding school when she got fired as a way to get her out of the show, but she was 17 and so isn't that a bit of a silly way to write her out? In Melbourne Australia, you can leave school if you wish at 15, so she in theory shouldn't be able to be forced into going to Boarding School.
Saga of a Star World (1) - S1-E1
Plot hole: Apollo takes Adama down to the surface of Caprica aboard his Viper, yet the Viper is a single-seat fighter. This is the only time the single-seat craft is used to carry two people (though there is no shot of the two aboard - it is simply shown landed with the two characters nearby).
Suggested correction: It was 2 seater Viper training aircraft.
