In Band's Best Friend, Stella is mad at the return of Joe's friend Carl, who poured pudding in her purse, and Joe said guys do mean things to girls because they have a crush on them. By the end of the episode it is revealed it was Joe who put the pudding in her purse, but when Stella asks him if he has a crush on her, he hurries away to perform. In Frantic Romantic, when Fiona Skye is harrassing Joe, Stella agrees to be his fake love interest, but when Macy suggests they kiss, they both refuse to do it. Later in the episode when yelling at Fiona, Stella lists things that she likes about Joe. However, when Joe's asked to do the same about Stella, he hesitates, and leaves. Joe is constantly jealous of Van Dyke's interest in Stella, and in Fashion Victim when the two are due to go on a date, Joe ruins clothes Stella made in order to make a fashion emergency so Stella would have to cut her date short. Later on, Nick informs Joe that a girl Joe somewhat likes wants to ask Joe out, and Stella gets jealous, saying he can't go on the date. However, when in Double Date Stella and Van Dyke go out on another date, Joe brings Macy along in order to ruin it. Joe and Stella later get into a fight over it, and Joe says that she is gorgeous, so adorable she makes him sick, and suggests he hasn't asked her out because he likes her, and didn't want to ruin their friendship, then they kissed. The next day at school, Kevin and Nick see them kissing, which means they have presumably started dating.
