Plot hole: For such a dangerous serial killer, Lt. Cobb should be more securely restrained than he is. He wears a simple pair of handcuffs, with only one security escort.
Continuity mistake: Right at the end, the dying Poloma reaches up and touches her brother's right cheek. Her bloody fingers leave a trail behind. This disappears in the next shot when Alejandro turns his head to look at Gibbs.
Continuity mistake: The writing on the board changes style at the very start. Note the 1st A in Satan. (00:00:15)
Visible crew/equipment: When Gibbs tells the team to gear up because there's some kind of gas leak at Quantico, at the start of the first shot at the high school, the blue tape mark is visible on the floor between McGee's feet. (00:03:05)
Continuity mistake: When speaking to Conrad about taking the internship at NCIS, the clock behind Conrad changes drastically. (00:04:25)
Visible crew/equipment: While Gibbs and Ziva are interviewing the teacher in the classroom at Quantico, in the wide shot facing Ziva as she confirms the number of students, there are two red tape marks on the floor beside the two back legs of her chair. (00:05:20)
Continuity mistake: When we first see Mason he puts his hat on the table by his phone. His hat then disappears from the table only to be replaced by Mason when Gibbs walks in. (00:06:20)
Continuity mistake: When the grandfather is talking to Bibbs and gets the phone call his hands/arms are off the table. As the shot changes to a longer one, his arms are now on the table. (00:08:09)
Continuity mistake: The way Abby holds out the bells for the intern to wear changes depending on the shot. In one shot she has the string over all 4 fingers and in another only over 1. (00:09:20)
Factual error: When McGee tracks Mason's first phonecall, he says the line has been forwarded to a skype number. When he does the IP address shows up on the screen as 212.11.256.192. An IP never goes over 255. (00:11:40)
Short Fuse - S8-E3
Other mistake: Tony logs into Abby's email, however he mis-spells her surname on the login details. He spells it Scuito when her name is spelt Sciuto. The I and U are the wrong way round. (00:06:00)
Short Fuse - S8-E3
Audio problem: When we first listen to the 911 call, the woman says, "there's no rush" however the audio playback bar is at a point on the screen that shows no spikes in the pitch. (00:06:40)
Short Fuse - S8-E3
Continuity mistake: When the bomb timer is discovered, Dempsey is stood next to the bomb as seen on Monitor 1 of the control room. The camera pans across, past monitor 2 and onto Monitor 3 which is still the same room but a different angle. On Monitor 3, Dempsey is now around 3-4ft away from the bomb. (00:14:00)
Short Fuse - S8-E3
Continuity mistake: When Gary's wife is talking to Fornell and Gibbs, she either has her hand on the rake handle or lowered depending on the shot. (00:24:30)
Factual error: When Tim is tracing the British agent's mobile phone it shows that the number traced is a British land line number (01632) not a mobile number (starting 07...). The number is also seven digits long, not six as is the format in the UK.
Broken Arrow - S8-E7
Continuity mistake: At the start, the way Ziva holds her passport differs when McGee asks to have a look at it. Note her middle finger is on the back of the passport and visible at the top in the middle. However, from behind, her hand is not on the back of the passport. (00:01:50)
