When David, Donna and Kelly are helping Mel and Jackie with their invitations they are wearing the same clothes they were wearing in an earlier scene at school. However, if this storyline follows the same time frame as Brenda's this event does not take place until a few days after the aforementioned day at school.
Border Patrol Officer: Hey, I'm sorry, but we're gonna have to get a legal guardian down here with your birth certificate or, failing that, they'll have to sign a sworn affidavit verifying you a citizen. Unless, maybe, you're not an American citizen.
Brenda: Of course I am. It's just that if you call my parents, I'm a dead American citizen.
Kelly: (to Jake) You can get personal if you want to.

While helping Brenda with her scheme, Donna mentions a troublemaking cousin. This could very well be Gina Kincaid, who does not appear until season nine.
Grant Show's appearance as Jake Hanson was a not-so-subtle introduction to the 90210 spinoff Melrose Place.
