Theres a costume ball coming to Bayside and everyone is excited about it. Unfortunately Kelly is in need of money so she goes to The Max for a job. There she meets the boss, a college guy named Jeff, and she gets pretty much hired. You can tell that Jeff is into her from the few verbal encounters they have. This ultimately leads to a kiss between them that is tough to stomach knowing that it ruined the great couple that was Zack and Kelly. Zack starts to realize that Kelly is becoming distant but doesnt know why. He finds out soon enough. At the costume ball Zack and Kelly win king and queen and while theyre accepting it together Kelly accidently calls him Jeff. Zack tells Kelly to come outside with him so they can talk. Kelly tells him that she has feelings for Jeff. The episode ends with them breaking up but Zack saying that they will remain friends forever.
This episode is definately one of the toughest ones to watch because of the outcome of it. I know the writers had to break up the couple sooner or later but i hated that it ended up being over a duck like Jeff. My point is proven a few episodes later when Kelly catches Jeff at a night club in an akward situation.
