Continuity mistake: Episode 6.4, Libra Slayer: In the opening scene, in the hospital, the man leans over the dying patient to hear what he has to say. His cheek is almost touching the patient's lips. Then the angle changes and their faces are suddenly quite far apart.
Plot hole: In this episode, the Duboises make such a big deal about Ariel being old enough to finally learn to drive. However, two episodes previously ("Things to Do in Phoenix When You're Dead") Ariel drove to school with Joe, and Joe complimented her on her prowess.
Allison Dubois: It's 9:00. How am I supposed to know you're OK? How do I know you're not lying dead somewhere?
Joe Dubois: If something had happened, somebody would've called. If I were dead, who are we kidding, you'd be the first to know.
Trivia: In the episode "Mothers Little Helper" When you see the front of the refrigerator, the word HARLO is visible on it, Patricia Arquette's daughter is named HARLOW, fitting for a storyline about mothers and daughters.
