At the beginning of the episode, Brennan tells Booth that "phenolphthalein doesn't lie" to indicate that she found blood. However, it effectively did lie when the phenolphthalein test gave a false positive due to presence of potato proteins in an earlier episode of the season.
When Brennan and Angela are talking about Daisy cheating on her partner with Sweets, one of the hand held steamers in the background changes position and angle between shots.
One of the workers who discovers the body incorrectly makes the sign of the cross, going head-left-right-heart. Since these characters appear Latino, in the roman manner, it should be made going head-heart-left-right. Even in the eastern manner, it is head-heart-right-left.
When visiting the bridal shop, the owner calls Anya a bridal consultant. But when Booth questions her, she describes doing alterations on the dress, which means that the owner should have referred to her as something along the lines of a "alterations consultant", or "seamstress".
When Dr. Brennan is telling Dr. Sweets that she believes Daisy is cheating on him, the camera alternates between shots of Sweets from Brennan's left and shots of Brennan from Sweets' right. We can see the right side of Sweets' cheek in the foreground of shots taken from his right and, at the end of a few of these shots, he begins to speak though his cheek remains still.
