One day, after Jamie O dropped them off at a restaurant to eat lunch, they see Sharice and overhear a conversation between her and her friend that she does not really like Jamie O and was gonna milk him for all he is worth. Gerald tells Arnold not to say anything about it to him because they're worried if he told them that he'd stop being nice and would not drive them to an upcoming hockey game. Days later Jamie O is seen doing Sharice's laundry and making her a soufflé. While juggling to do all those things, Jamie O accidentally burns one of Sharice's cashmere socks and breaks down crying. Feeling conflicted, Gerald decided to tell Jamie O the truth about Sharice and he doesn't believe him until he overheard her talking to her friend that he's a sap, causing Jamie O to realize that Gerald was right, and as a result, Jamie O broke up with her offscreen. The next day, to show that he's sorry for not believing his brother, Jamie O drives Gerald and Arnold to the hockey stadium.
