 * This episode marks the return of a running gag which was popular until the Best Wishes series: A character proposing to an attractive female. However this gag has a new twist to it: Bonnie would ask the female to be Clemont's girlfriend but Clemont would intervine saying he's not interested and he would use his Aipom Arm to drag Bonnie away.
