Factual error: Lane wants Rory to talk to Dean about setting up Lane with his friend Todd. While asking Rory to do this, Lane asks for the date to be planned for the following Sunday, after church; however, Lane is Seventh-day Adventist and they believe the Sabbath is Saturday and therefore attend church on Saturday, not Sunday.

Continuity mistake: Kirk did not know who Miss Patty was. He said "I wasn't aware that you were THE Miss Patty." Later in the series, in Episode 5 of Season 6, at Miss Patty's Grand Recital, Miss Patty introduces Kirk's performance and says that he was "a talented pupil of mine". His performance was titled, "20 Years Ago Today", therefore Kirk was a student and should have known who Miss Patty was all along.
Other mistake: Rory is seated on the front steps of Dean's house. A car pulls up to the curb. Dean gets out of the passenger side of the car. But we didn't see, is anyone get out of the driver side or going into the house. I am assuming that Dean's mother or father picked him up. If that's the case, then why didn't they pull into the driveway? Had he used a car service, he most likely would not have been seated in the front seat.
