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.
Continuity mistake: Allison wakes up with an address in her hand, but when she later shows it to Scanlon, the writing is in a different position on the paper, and the paper does not show the folds it had earlier.
Continuity mistake: At the end when they are confronting Harmony, they pick up the water glass for DNA testing. In the next shot over her shoulder, the glass is still on the table. (00:36:55 - 00:38:09)
Continuity mistake: When Allison wakes up from her dream about the murderer, she runs into the kitchen to write down the car's license place on a notepad: 2TH DOC1. However when she holds it up to show Joe, it's smaller written and not across the notepad as she had originally written it.

Continuity mistake: When Allison is in the shower, she has total use of her right arm, hand, wrist and fingers, where in all scenes before and after she holds her right hand and fingers close to her chest and doesn't move her fingers and hand freely.
Will the Real Fred Rovick Please Stand Up? - S6-E14
Plot hole: Joe says that he and Allison told people they conceived Ariel on the weekend of their wedding, even though they knew that Allison was about five weeks pregnant at that time. In episode 6.15 the plot is all about how Allison is expecting Ariel and there is a lot of talk of how she is their first child and they can't tell anyone about it because they aren't married yet. But in the season two episode "Sweet Child O' Mine" it was revealed that they were going to have a baby once before Ariel, a boy they were going to name Brian, but that Allison miscarried.
Suggested correction: What exactly is the point. She was pregnant and miscarried. So? That's not a mistake.
