The Heart Burglar

S3 E25: Sarah is teamed with Sean as a study partner for physics. And Jamie guesses that Charles really likes Carol, Buddy's girlfriend; and Carol, in turn likes Charles; and Sarah likes Sean. All the while, Sarah emphasizes that Sean is strictly a 'study-buddy.' Buddy asks Charles to pick up Carol and they will all meet at the Powell house to go to the basketball game. When Sarah learns that Sean is coming by the house that evening, she takes more effort to dress nicely -- then becomes furious to learn that Sean is also going to the game. Following the game, Carol kisses Charles, and they admit their attraction for each other. Then Buddy tells Charles he wants him to date Carol because he and Carol really have nothing in common.
