Factual error: After Gerald gets back to NCIS HQ, he notes that he wasn't able to drive Ducky's Morgan; a stick. Abby brags about knowing how to drive a stick since she was ten. When asked what she drove that had stick, she answered, "Red '47 Ford half-ton with four on the floor and Bubba riding shotgun." When asked who Bubba was, she answered that he was the best coon dog in Jefferson Parish. If in fact Abby grew up in the city of New Orleans, as stated by McGee in the episode before, the dog would not have been the best coon dog in Jefferson Parish but Orleans Parish. No part of New Orleans is inside the Parish of Jefferson. If it was truly the best coon dog in Jefferson Parish then Abby would have lived in Metarie or Kenner, Louisiana, both of which are inside the parish limits of Jefferson Parish.
Kill Chain - S11-E12
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.
Suggested correction: Ellie correctly says, "I'm Ellie Bishop," when she introduces herself to Delilah. I slowed the speed down to 0.5x to confirm.
