David is walking Kelly, Donna and Steve through his grandparent's house. Just as they walk past the stairs, a member of the filming crew can easily be seen in the mirror in the middle of the room.
In this episode Donna tells Brenda she will really like sex. Later on in the series a major plot line is that Donna is a virgin.
Brenda: I'm a normal female, you're a normal male, we all have needs, so let's just do it.
Brenda: Dylan, just shut up, and take your clothes off.
Donna: High school guys, college guys, grad school guys, drop guys. You can not dress the same for all guys.
Brandon: Ever get the feeling the entire world is flying in first class, and you're stuck with a folding chair in the baggage compartment?
When David is showing his grandparents' house to the gang, you can see a crew member's reflection in the mirror on the wall.
