Cody and Barbara occasionally go on study dates, and once went mini-golfing. In the episode Orchestra, they were dating, and shared a kiss. In the episode Graduation, the two are often talking about how they want one another to be class valedictorian (and Barbara stomping on Cody's feet), even though them, themselves want to win. They even make a bet that the loser will give the winner a kiss. It's obvious when he tries to impress her. He even preformed a traditional Japanese tea serving ceremony for her and her grandmother. She's the girl on the show who is there to be Cody's ideal girlfriend.
