Continuity mistake: While trying to restart the engines after the ship is hit by the nuke's EMP, Chandler is checking the fuses while Chung is going through his checklist. There are only five visible fuses in the six available slots in the panel that Chandler is checking. After he gives the order for Chung to "give it a kick-start," the slot which previously had no fuse now does, only for it to shoot out from the start attempt.
Revealing mistake: At the river to cross over to Mt Weather, the vine used to swing across the river is just a standard rope, camouflaged. You can see it best when Finn recovers it after Jasper has jumped.
Insane in the Membrane - S2-E6
Visible crew/equipment: After Hamilton tells Pride that he will arrange for Kendrick's grandmother to stay at the assisted living facility in his district, when it cuts to Kendrick and Percy walking toward Pride the red T-mark taped to the rug can be seen at Pride's feet.
True Colors - S1-E6
Continuity mistake: Walter and Paige begin dancing and there is a lady dancing in a green dress behind them. In the next frame, that same couple is dancing across the room and then a second later next to Walter and Paige again. Walter's left hand holding Paige's in a dancing position also changes from open to closed. (00:26:05)
The Saint of Last Resorts - S1-E8
Continuity mistake: John throws some stones onto a table to investigate whatever took the baby. The angle changes and they're in a completely different arrangement.
The Thing About Heroes - S5-E2
Other mistake: Officer Burgess kicks in a door with a lock and deadbolt and does no damage to the door frame. (00:46:21)
Just Another Normal Day - S1-E4
Continuity mistake: In the morning kitchen scene with the kids eating breakfast, the daughter bends down and grabs a blue box of cereal from the bottom cupboard. Next cut from the opposite angle, shows that she now has a yellow box of cereal instead. (00:12:25)
Revealing mistake: When Iris is sitting in bed recording the message for Barry, she is holding her iPhone so that the start button is on the left side, but the "video record" button appears on the right. Additionally, her right hand covers the speaker area of the phone fully, including the front facing camera. It is impossible for Iris to be recording the video live and reveals that the video footage was recorded ahead of time. The illusion that the video is being recorded by Iris live is further ruined by the fact that the room lighting is turned off in the scene, but the recording is well lit. (00:02:55)
Who Shaves the Barber? - S1-E7
Continuity mistake: When Molly visits Wes Wrench in the hospital we see the whiteboard on the wall has writing on it. Molly takes it off the wall and hands it to him without erasing it and it's suddenly blank.
Legend of the Dark Knight: Ruin - S5-E4
Continuity mistake: When Ed is trying to take the Blackgate folder from Lucius, the way it's held between them changes between shots.
Visible crew/equipment: When Molly walks into the "memory lane" tent at the carnival, four shots in we can see the reflection of a crewmember (moving dark silhouette) on the glass display beside the entrance. Then as Molly turns the crank and looks into the Mutoscope, in the wideshot we can see a crouching male crewmember hiding behind the case, at the left side of the screen. (00:28:15)
