Goof: At the very beginning of the episode, as the camera pans up from the body to the delivery driver, she blinks.
Duane Henry (Jenkins) is promoted from recurring to main cast starting with this episode.
Chris Pacci was not o the wall of deceased agents.
When we first see Tali in the park, her legs are sticking out and she has no blanket on her, yet in the side view scenes between Tony and Tim her feet can't be seen and there is a flat pink blanket where Tali is supposed to be.
In So It Goes (season 12 episode 3) Ducky tells Bishop that the last time he saw his friend Angus Clarke was at his going away party, yet this episode shows them meeting again years later.
There is a typo on the analysis report Abby holds when entering Autopsy. Instead of "specimen analysis summary", it says "specimen analsys summary".
Guest Bart Johnson is married to Robyn Lively who appeared in the pilot episode, Ice Queen and Meltdown which was on JAG.
When Gibbs sees the ghosts of other dead NCIS Agents, Macy (NCIS: LA) is not there.
Gibbs said that he worked on the undercover op which took place when NCIS was still NIS which was before 1992, with Mike Francks and Jenny Sheppard. But didn't Francks and Sheppard first meet in the episode Hiatus which was in 2006. And Gibbs didn't meet Sheppard till he worked with her on the Paris mission in 1999.
Just before Sergei tries to shoot Fornell in the cabin, Fornell makes the same arm gesture Gibbs did in Kill Ari pt 2 just before Ari tried to shoot Gibbs.
In Season 12, Episode 11 "Check"
On the bio profile for Diane, ex-wife number one, the second to last input states she slept with McGee. What is the backstory on THAT!
The input just before that states that Gibbs gave her a waffle iron for a wedding gift.
Tony tells Bishop that he's managed to miss the Sexual Harassment Seminar held by NCIS every year, yet in Driven (Season 4 episode 11) we find Tony sitting in on one.
GOOF: During the Gibb's first flashback of him and his Father, we see Gibbs around the age of 6 walking through a water puddle holding his Father's hand. As Leroy Jethro Gibbs' birthday is May 2, 1958 ("Heartland", episode number 117, season 6, episode 4), this would put this scene around 1964. The goof comes from the pair of shoes he is wearing, as they clearly could not exist in the 1960's. He is wearing a pair of Converse Chuck Taylor All Stars sneakers. In the 1960's the heel logo was a dark blue/black with multiple stars (one large star with 2 smaller stars on either side). The pair of Chucks young Gibbs is wearing has a white rubber logo with black lettering saying "ALL STARS." This logo and its variations didn't start till the late 1980's a full 20+ years later.
Charles Schlater, who plays the clinic director (and ultimately the villain) in this episode, played Dr. Jesse Travis in seasons 3-8 of the long running 1990's and early 2000's TV series Diagnosis Murder, which also starred Dick Van Dyke, Barry Van Dyke, and Victoria Rowell. Part of this episode's plot, namely the harvesting of homeless people's organs, is reminiscent of the Diagnosis Murder Season 3 episode entitled "Living on the Streets Can Be Murder". In that episode Dr. Mark Sloan ends up going under cover as a homeless person to try and stop a killer from killing homeless people in order to harvest their organs.
The bar seen in this episode is the same bar seen in "You Better Watch Out" (season 10 episode 10).
When Jimmy handled the i.V. flow of Troutman,trying to increase the drug flow and falsely called "oxycodone" a sedative, it would not have worked. Oxycodone does NOT come in liquid form and is therefore never entered into an i.V. bag. So: double GOOF.......
Jimmy called "Oxycodone" a sedative. Big GOOF. It is a painkiller. Sedatives are either barbiturates or benzodiazepams. An assistant ME and future MD should know. So should the writers.
Zoe Mclellan played PO1 Coates in JAG and has met Gibbs before as her. She returns to the NCIS world but as a different character.
Nitpick: DiNozzo tells Bishop that Gibbs doesn't play games except for Twister, which he says was confirmed. He forgot to mention that he also plays chess, as seen in "Devil's Trifecta" (10x09).
When Bishop uses her car to stop a fleeing suspect, Tony tells Gibbs that she "pulled a Palmer." This is an allusion to episode 5x17 "About Face", wherein Palmer broad-sided a fleeing suspect's pickup truck with his own SUV.
