I thought of a few more continuity errors. i know the couple that have been talked about are the one with Jo and the season 1 girls in Little Chill and Jo's grandfather in Rites of Passage. A few more I've thought of; in The Secret Jo said her dad was about to turn 40, yet in Something In Common she said he was turning 52,which was 7 years later, so the math was off five years. Also. in Molly's Holiday Natalie mentions her parents getting divorced and getting together again when she got sick and they may get married again, yet in The Affair she talks about their silver anniversary, saying they'd been happily married coninuously the whole time.

Most of the continuity errors I've noticed are in regards to the characters families.

Tootie had a brother who was mentioned and seen like once. Most of the time she seemed like an only child.

Blair's Cousin Geri had two different last names. Sometimes it was Tyler and sometimes it was Warner.

Blair's mother wasn't played by Marj Dusay in her first outing. (I think?)

Another one I thought of was in New Girl part 1 Blair maneions the Chug A Lug as being 5 miles away, yet in the last episode when the kids sneak off there it's implied as though they walked there.

There were a few errors with the Eastland headmasters. In the second season there's no mention of Mr. Bradley. Everyone accepts Mr. Harris as the new headmaster no questions asked. Another error was with the season 3 episode where the girls get caught drinking in the dorm. When Mrs. Garrett threatens to tell Mr. Parker about what happened, Natalie pleads with her not to, arguing that he expelled students the previous year for the same offense. The thing is he couldn't have because Mr. Harris was the headmaster the year before season 3...
