Gotta Be Me - S2-E22
Factual error: When Luis is in the video store, they pan out to show the video rack he was looking at. They show Disney's Tarzan on one of the racks. Being that this show is set between 1995-1998 for all 4 of the seasons, Tarzan should not be on the shelf as it was not out until 1999.
Continuity mistake: While Jessica and Louis plan their upcoming week at the dining room table, Jessica's hand (and the pen held in it) change positions as the camera angles change.
