Continuity mistake: When Tori joins the group during the final season, she and Zack date for two episodes, but they are not in sequential order.
Saved by the Bell (1989)
1 continuity mistake in Season 4 generally - chronological order
Starring: Mario Lopez, Mark-Paul Gosselaar, Dustin Diamond, Lark Voorhies
Visible crew/equipment: After the fashion show when Zack says "Sorry Lisa, I don't know what to say" an entire boom microphone assembly is visible and snatched out of view at the top of the screen.
Mr. Belding: Go to class, learn something.
Trivia: Of the main six characters, Screech is the only one whose father never made a physical appearance on the show.
Question: What happened to Kelly and Jessie in the episodes with Tori? Can someone explain what went on there.
Answer: As far as I can tell Jessie and Kelly decided to leave the show because their contracts were up and they wanted to pursue other things. But there were still episodes of Saved by the Bell left to tape so Tori came along to fill that void. Jessie and Kelly were supposedly still at Bayside, but they were "off-screen." The Graduation episode was filmed before Kelly and Jessie left the show.
