Continuity mistake: Taz (lead singer of group Donna and David are producing a music video for) recognizes Kelly from her 'Seventeen' magazine cover and mentions it was in spring (May) 1994; however that was still the gang's freshman year in college (Season 4) and Kelly did not do the Seventeen shoot until season 5, and the magazine cover was out in the spring of 1995.
Continuity mistake: When Steve is talking to Valerie, after getting out of the shower, about Coming Home early to surprise Claire, you can see shaving cream on his ears. When the shot changes to a side view of him sitting on the bed, he no longer has the shaving cream on his ears. When the shot changes back to looking at him head on, the shaving cream is back on his ears. This goes on for the entire scene.
Continuity mistake: When Donna talks to David about their childhood, Donna's hand moves from stirring her drink to resting on her arm between shots. (00:04:15)
Continuity mistake: In this episode, a main story line revolves around Steve and Kelly's supposed first and only sexual encounter, at the beach club while they were in high school. Sorry, but the early episodes made it clear that they slept together many times while dating, and The First Time was in Steve's room while his mother was being interviewed downstairs.
Character mistake: When he arrives at his hotel room in Vegas, David is surprised that Ray is performing at one of the casinos. But at the beginning of the episode, Steve told Brandon that Ray was performing, which suggests going to see him was part of their plans. So either (1) Steve shouldn't have known Ray was performing there, or (2) David shouldn't have been so surprised.
