I thought her crying seemed a bit over dramatic to be honest. its not like she's never gonna see him ever again, its only 4 days till the next beach party. but i understand that she's been spending all her time wiv him, and so not seeing him everyday will be a bit of a shock.
If you thought that was over dramatic then wait until some of the later shows, haha - there's much worse. What Kevin wrote was right, it might seem minor now watching it back but at the time it was our entire life's and you build very strong bonds with people in short spaces of time.
