They become friends; encouraged by her best friend to invite him to the Morgan family farm. He not only makes a good impression on her parents and brothers but triumphs in the rustic lawnmower race. Only after some paparazzi track Edvard down to film them kissing and he has returned home because the king is gravely ill does Paige realize he may be her true love, and flies to Copenhagen.
