Love is in the air! Julie and Roland are an official "couple," which means . . . well, they're not exactly sure what, except that it makes Papa Dad extremely anxious. Meanwhile, Lydia's mum announces that she's marrying Coach Eric (the football coach from England) and Lydia and her sister, Melody, are not happy about it. With the wedding date looming, the girls will have to figure out how to accept the inevitability of change-and realise that even if the change seems terrible at first, it can still end up all right, as long as you have good friends at your side.
