When Booth and Brennan are questioning Dunwood in the interrogation room, the top of a wine bottle can be seen sitting on the table when the camera faces Dunwood. The camera switches to a shot of Booth where we see him pick up and hold the bottle. The camera then goes back to the shot of Dunwood and we can see the top of the bottle on the table again. When the shot returns to Booth, he is still holding the bottle as if he had never set it down.
When the intern is with Hodgins and the watermelons he has his hands in front of him but in the next scene he has one hand near his head.
They determine the injury was caused by a 9 1/2 inch diameter wine bottle but the ones they test are clearly not that big. More like 9 1/2 inch circumference.
When Booth and Brennan are in the car after Cam talks to Booth about his potential sperm donation, we can see the scenery on each side of the car. While the camera is on Booth, the scenery reel ends, switching instantly from a building to park scenery.
When the wine barrel was being examined it was revealed that the wine had turned into a viscous vinegar-like liquid. This would have been noticeable during the wine tasting as would the rancid smell.
Booth is diagnosed as having a brain tumor when he has hallucinations of Stewie Griffin from Family Guy (1999). Other instances of Booth's hallucinations are given as further evidence of the tumor, such as his having seen an old military comrade, Teddy Parker, in a previous episode The Hero in the Hold (2009). However, Brennan also saw and interacted with Teddy Parker in that episode. If his appearance were truly a symptom of Booth's tumor, Brennan would not have seen or interacted with him.
Hodgins claims to find a "grommet" when sifting through the goo. Bones asks for it, he hands her a toupee screw. A grommet is a metal ring used to protect a hole in cloth.
Cam counters Hodgins' ruling out a Bedford Creek bottle as the murder weapon by pointing out his earlier determination that the glass fragments came from the same bottles.
Cam wasn't in the room when Hodgins made this discovery and therefore could not have known the origin of the fragments.
