Annie loathes receiving an invitation to Simon's 'disaster' wedding to Rose in May, until she realizes that's the same day as Matt and Sarah's med-school graduation. Neither group will even consider another date, arguing that the other event is less important or troublesome. Ruthie considers taking a summer poetry course in Scotland to be with her ex Peter, but Eric won't pay and the phone-bill hits hard. Kevin plants the romantic idea of eloping. Rose's jealous ex Bert grills Simon about his mystery girlfriend and questions his commitment; Annie finds out and teams up with Bert, who talks Rose out of eloping as the Camdens would ruin this by attending. Yet the changes of plans and the truths that turn up inspire surprising changes of heart.
