Rockets, Communists, and the Dewey Decimal System - S1-E2
Other mistake: As Young Sheldon is a prequel series to Big Bang Theory, this episode is at odds with episode 2-13 of Big Bang Theory, "The Friendship Algorithm," in which Sheldon is unfamiliar with books like "How to Make Friends and Influence People," which he reads in this episode of Young Sheldon, produced nine years later but taking place twenty years earlier.
The Austere Academy: Part Two - S2-E2
Continuity mistake: In season 1 whenever count Olaf's tattoo is shown, it is always on his inner left ankle (the reptile room part 2, Mr. Poe wipes the makeup to reveal it on the inner ankle, and In the Wide Window part 2 when Sunny chews through the broomstick and Olaf's lag is revealed it is also on the inner ankle. In this episode, after Sunny loosens the laces on Olaf's shoe and the Baudelaires defeat Olaf in the arm wrestling, the tattoo is on the outside left ankle.
Factual error: The briefer on the oil platform mission says the platform is 12 stories, and 80 million square feet. Doing the math, that makes it half a mile per side if completely square. It is nowhere near that size as shown. The largest oil rig in the world - Berkut in Russia's Far East - has a combined deck area of only 342,000 square feet. (00:13:35)
Old Wounds - S1-E1
Continuity mistake: When the Krill shuttles land, they park on either side of the entrance to Epsilon station, but when the Orville crew are escaping, the Krill shuttles are gone momentarily (during the firefight), only to return to their proper places a moment later as the Orville shuttle takes off. (00:33:40)
Always Waiting for the Next Bad News - S3-E9
Continuity mistake: Jessica is wearing a massive earring, but when the camera is behind her, she isn't. (00:23:38)
Factual error: In the opening sequence when Maddie is supposedly driving from Michigan through Ohio and back to Pennsylvania, you can very briefly spot the reflection of a "TD Canada Trust" in the car window. This is because the show is actually shot in Vancouver. In the United States the company is simply known as "TD Bank", which doesn't operate any branches in either Michigan or Ohio. (00:01:55)
Other mistake: In the hotel room shootout, bullets are being fired through the wall easily and tearing up the place as you'd expect. Frank then dives through the damaged wall and they shoot at each other with Frank behind a cupboard and Pilgrim behind an internal wall. But bullets empties into both of these bits of flimsy cover leave the men behind them miraculously unscathed.
Episode #1.7 - S1-E7
Factual error: Lorna uses the word 'okay'. The first recorded usage of this word in America was not until 1839 and in Britain not until the 20th century. The series is set in 1814 and generally uses language contemporary to its setting.
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?
Continuity mistake: When Midge is doing her makeup routine, she doesn't have eye liner, then she does, then she doesn't.
Continuity mistake: Right before Wendy sends the email that her husband is dead, a can of shaving cream can be seen on the right side of the sink. After hearing her husband come into the hotel, she knocks over the can of shaving cream, which is now on the left side. (00:47:05)
Trigger Time - S1-E3
Continuity mistake: During the shoot-out near the end, the bullet holes in the pillars Frank and Kyle hide behind change and also disappear at various times. In one shot we see 2 holes when Kyle steps out to shoot, then when he ducks back when fired upon, the 2 holes are gone.
Continuity mistake: In season 4 of Prison Break, Mike Scofield's tombstone date of death shows 11-4-2005 but in this the date is 11-4-2010.
Factual error: In several different episodes characters are escaping on foot to Canada, as evidenced by Ontario license plates. But the show is set in New England, and the only way to get to Ontario through the Eastern United States is by crossing a major body of water: The St. Lawrence River, Lake Ontario, The Niagara River, or Lake Erie. You can't walk there.
Plot hole: Michael uses herself as bait to trap her future self, putting her own life in jeopardy with the reasoning that her future self will come back to save her. All well and good, except they have a backup plan with the doctor to resuscitate her if needed, meaning her life isn't really at risk, or nowhere near as much as might be implied. And her future self would undoubtedly know that, having lived through it in the past, so not swoop in to save her. Or even if she did come, would also know it was a trap.
Suggested correction: ***SPOILER ALERT*** But, as it turns out, The Red Angel that comes to save her is NOT Michael, but her mother, who would not necessarily have known about the backup plan.
***SPOILER ALERT*** That it was her mother doesn't stop it being a plot hole since they thought The Red Angel was future Michael, and future Michael would know that present Michael wasn't really in danger so they weren't presenting a situation, _according to what they believed_, that required future Michael to act. It being the mother was a plot twist that created a motivation to act that the present people had no reason to think would exist. Basically, unless they presume a split timeline (i.e. this present is a different past than The Red Angel lived through), making a trap for future Michael that present Michael is involved in makes no logical sense.
Alternatively, Michael would have to come back, KNOWING it was a trap, to prevent the timeline unravelling.
The point of the exercise is they were setting a trap. If it didn't work, then Michael wouldn't have to come back to "prevent the timeline unravelling (sic)", even if that were a thing - it presupposes a fixed, unalterable timeline, which goes against their attempt to send the data to the future to protect it, and thereby alter the future. Even with an unalterable timeline, it would only work if future Michael had chosen to allow herself to be trapped, but in that case why wouldn't future Michael just voluntarily come back to help? Since her being trapped wasn't a certainty, there was no reason to think she would be given that the current Michael, and therefore also future Michael, knows a trap has been set, but one that doesn't actually threaten current Michael. The whole premise of the trap, under their assumption that The Red Angel was future Michael, is completely flawed and made no logical sense.
The fact that The Red Angel was in the future, and that they had a backup plan meant that The Red Angel never should have come back in time, ever. Because the backup plan would be the recorded history, thus, she never would have died. Thus, nothing to save. Face it, everything in Discovery is a plot hole.
Other mistake: When Jessica calls Hondo to let him know about Deacon's wife, you see Hondo answer the phone normally. Right after she tells him what's up, you can see him holding the phone upside down, with the camera lens towards the bottom. (00:24:30)
Continuity mistake: Gandia dislocates his right hand thumb/wrist to free his right hand from the handcuff as shown from the back but the next shot shows a free left hand instead.
Factual error: The show has a BMW X5 (2007 - 2012) appearing when the media goes to the brother's house. (00:27:50)
Continuity mistake: Outside Rusty's bar Lucy says she's staying in room 114 of the Marlowe Inn. When Brockmire goes to see her, she's in room 411.
Out of Time - S1-E3
Continuity mistake: When John meets Brooke and is examining her wrist, he ends up holding her hand palm up, but in the next shot her palm is facing down.
