Bones

The establishing shot of the fictional University of Hogansburg is in fact the Valley Life Sciences Building at UC Berkeley.

This is the first time Bones never worked on a single bone. This is also the first time she did not step one foot into the Jeffersonian during a murder.

Joseph is Seeley Booth's middle name.

Angela changed the name her father gave her (which was "Mouse") because she hated it. (In season three she said that she legally changed her name on her 18th birthday after the name 'Angela Montenegro' came to her in a dream.)

Booth's supposedly record-holding shot of "over a kilometer" (over 0.62 miles) would be considered unexceptional in the real world. Modern snipers regularly and successfully operate at that range, and (as of the episode's air-date) the record for the longest confirmed kill made by a sniper is 2.475 kilometers, or a little over 1.5 miles.

When Sweets is working out in the beginning of the episode, he's listening to "Coconut" by Harry Nilsson. This foreshadows the episode "The Hole in the Heart" when the song has a more prominent role.

The paper that Bones is holding in the elevator shows the zip code for Washington, D.C. as 20014 when in fact there is no such Zip Code. There is a 20013 and a 20015 however.

175-180 centimeters does not correlate to 5'8-5'9, more like 5'9-5'11.

The study that Micah mentions in the bone room with Dr. Brennan seems to be a study from the Journal of Perception entitled "The myth of upright vision. A psychophysical and functional imaging study of adaptation to inverting spectacle." [Journal of Perception, 1999, volume 28, pages 469-481. Linden, David E J, et. al.]

GOOF: When Hodgins and Daisy are walking up on the platform, near the beginning of the episode, the camera zooms in to Hodgins scanning his card. His wedding ring is on his ring finger. However, after the cut to them walking across the platform his ring is on his pinky finger where it normally is.

GOOF: As a licensed clinician Dr. Sweets should know that Multiple Personality Disorder (MPD) is no longer an acknowledged diagnosis. The disorder formerly known as MPD is now called Dissociative Identity Disorder.

Unless Angela had started revealing her pregnancy to everyone in the lab there is no way that Mr. Nigel-Murray could have known she was pregnant.

Goof: In season 3, episode 10, Sweets said that he loves dogs, and in this episode when he and Daisy tried to find common interests, he said that he is allergic.

Nitpick: Hodgins puts the bones in a tank and adds piranhas into the water to eat the pink organism off. Seconds later, he removes a bone and it is clean, but it is unlikely the piranhas could eat them in that time. Also, when Daisy asked for the ulna, Hodgins was able to easily pick it out. With the unclear, bubbling water, it would be hard to find a specific bone that fast.

Goof: 2 by 3 by 4 meters of concrete makes up a volume of 24 meters cubed. Considering the average concrete to have a specific gravity of 2.4, it should weigh about 57.6 tons. Not less than a ton like Bones says.

Goof: The 3D-printer Angela uses to create a 3-dimensional replica of the skeleton raises the already created print out of the plastic-liquid. In this way, the print is in the way of the lasers. Actually, the lasers heat and solidify the plastic point-by-point just below the liquid's surface. The print is then sunk by bit to enable the print of the next layer, allowing the lasers to reach their focus-points without being disturbed by already printed parts. The print-process normally takes a whole night for an print-object of the size of the skeleton, not just a few moment as suggested in this episode.

Also, the lasers used for 3D-printing operate at a wave-length not perceptible for humans (they are invisible to humans), and due to their dangerous nature, are being operated either in closed rooms or behind a special orange glass which prevents the laser-beams from exiting the work-area.

In the video of the bounty hunter and the bondsman, the supposed rib-breaking incident is shown. However, the jab with the pool cue and subsequent clutching of the injury is far lower than the fourth rib. As is shown in the episode, the fourth rib is up near the heart. The injury shown in the video appears to be to the stomach area (9th rib or lower).

Goof: While Sweets, Booth and Julian watch the video where the bounty hunter gets hurt, Julian mentions that the bail bondsman is terminal because he has cancer and that the diagnosis is not good. What she should have said is the prognosis is not good, since what she means is that he has little time to live–not that he was misdiagnosed.

Goof: Tutti the cadaver dog made his first appearance in Season One, "The Man in the Wall." However, the dog in that episode had a light brown coat and was indicated to be male. In this episode, Tutti is said to be female and has a black coat, yet it is hinted that this is the same Tutti.

The character Bunsen Jude is likely based on Bill Nye the Science Guy, who hosted a children's show of the same name about science.
