Character mistake: In the scene, where Jeanne tells Tony that he never said he loves her, besides after sexual activities. This is not true. In episode 15 "Friends and lovers" Tony ends a phone call saying "I love you."
Continuity mistake: When Abby is first discussing the victim's blood types, there is a shot from behind her that shows a black band wrapped around her upper left thigh about an inch below the hem of her skirt. The shot changes to a front view and the black band is gone.
Other mistake: McGee says that Jancy got into her cab at 12:37am and arrived at her destination at 12:55. That's 18 minutes for the taxi to drive "over 20 miles away" Hardly likely given traffic. (00:29:00)
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.
Character mistake: Ellie Bishop introduces herself to Delilah as Emily Bishop in the elevator scene. Her name's Eleanor in the series, but the actress' real name is Emily. She used her real first name in the scene.
Plot hole: Season 6, episode 8 ("Cloak"). When Ziva and Tony take the elevator two floors down this takes a full minute. When in a hurry for a call it speeds down, yet for this conversation it (conveniently) took a minute.
