Other mistake: When the show aired in 1990, in the pilot episode Brenda falls for Jason. She later on reveals herself to be a "16 year old junior" in high school. Season 2 opens up with the gang on summer break which technically would make them going into their senior year. It wasn't until Season 3 that they were going into their senior year. They graduated in 1993 from West Beverly but the show debuted in 1990 so technically they should have been sophomores.

Question: In the first few episodes, the Walshes live in a different house than the one they live in throughout the series. Nothing was ever even mentioned, I don't think. Was it a mistake, or did I miss the explanation?
