Visible crew/equipment: At about 30 minutes into the episode, right after Cal says: "if Jeffrey knows about priox, he's going to jail. But I'm gonna be damn sure before I send him there", you can see a hand in the top right corner of the screen.
Plot hole: The pictures James took were developed from his camera into photos even though he was arrested while taking those. How did they get developed? James' father didn't approve and his mother said she had found that stack of photos after the police searched his room. (00:26:30 - 00:30:00)
Continuity mistake: When Gillian and Eli talk with commander Markov about what happened with the X-48, he says "I was at the cruising altitude of 10,000 feet... Actually, ten-thousand-five."When they play back the recording, Markov says "actually, ten-thousand-five-hundred." (00:11:35 - 00:17:20)
Delinquent - S2-E16
Visible crew/equipment: In the shot of Eva in the blue car towards the end, a camera is reflected on the side of her door as it zooms in on her.
Continuity mistake: 1.08 (Depraved Heart) Lightman is working late and his daughter drops by to bring him Thai food. As she's walking towards her father, her arms are crossed. Cut to the immediate shot from behind, and her arms are down at her sides.
Continuity mistake: Right before Collette Bradley leaves Kimberly in the car, her car key is still in the ignition (the keyring is visible). But in the immediate shot of her getting out of the car, it is out of the ignition and on the seat next to her.
Continuity mistake: When Cal goes to tell Mr. Dawkins that his daughter has HIV, he brings a glass of water into the room with him. The glass is half full (or half empty, depending on how you look at it), but throughout the scene it keeps switching between half full/half empty and three quarters full/one quarter full.
Visible crew/equipment: When Cal and Ben go to the doctor's office, a cameraman operating a camera is reflected in the glass door as Cal and the doctor enter.
Continuity mistake: In the warehouse where Dave is being tortured, Cal says to Moon that he should get Dave to talk about shagging his mum. Moon then points his gun at Cal. In the shots of Cal the gun is held "gangsta style", i.e. horizontally. But in the shots of Moon the gun is held vertically.
Continuity mistake: In the scene where Emily finds her Grandma's diary, she leaves a message on Cal's phone about them having lunch together. As she hangs up, her fringe is tied back behind her right ear and falls down in front of her face, but in the next shot it is back behind her ear.
Continuity mistake: When Emily and her boyfriend Rick tell Cal that he loves her, Rick's hands switch from down by his sides to clasped in front of him between shots.
The Royal We - S3-E2
Revealing mistake: On the RV of the guy being accused of molesting the girls, someone has written "PERVERT" in red spray paint. At a point you see Lightman next to a car, and the RV in the background, and the text is mirrored reading: "TREVREP", showing that during editing, this shot was flipped. (00:15:30)
Continuity mistake: When Torres is holding the camera she puts it over her shoulder, but in the next shot the camera is in her hands again. (00:06:35)
Delinquent - S2-E16
Continuity mistake: After Emily hits the fire hydrant, we see water coming down on the windshield with great force. The shot cuts to outside the car, and we can see that the windshield is getting hit with water much less severely than it was a moment before. (00:02:55)
Fold Equity - S2-E9
Audio problem: When Loker receives a video file from Lightman, the shot changes to face Loker and Ria. There are about nine more "dings" that indicate a new item has arrived, but after the final ding is heard, the shot goes back to face the monitor and there are only five items on the screen, with more coming in.
Continuity mistake: When Terry asks Cal to sit in on the poker game with McClellan, there's a man in a brown jacket that walks past Cal three times. (00:04:05)
Continuity mistake: When Emily talks to Cal about occasionally visiting college bars to listen to the music, she crosses her arms over her chest twice.
