It's prom time, and while everyone is caught up with who's going with whom.
The seniors charter a yacht to Catalina, but Lo skips out.
Graduation day is here and the seniors spend time with their families getting ready for the big event. Through a Senior Video Project, the seniors reveal their personal thoughts on graduation, senior year, and life after Laguna.
Free from school, the gang lives up their last summer together, but when they gather for a final barbeque at Trey's house, the reality of leaving Laguna and each other starts to sink in.
In the final days before leaving Laguna, Stephen must tie up loose ends.
Kristin, Jessica and Alex H. are seniors now and plan on making the most of it, no matter who gets hurt.
Love and Laguna Beach mix like chocolate and onions. Things with Stephen and Kristin are dunzo, but what about him and LC? And rumors about Jason and Alex M abound.
It's a birthday weekend in LB, but LC is splitting with Kaitlyn, Stephen and Dieter to celebrate in Mexico, while Alex H. and Jessica throw a dinner for Kristin. Kristin's only request? Taylor is not there. She got it, and also a call from Stephen and a little something started with Talan. But a Happy B-day turns to tears for LC when Stephen heads back to San Fran.
Things are heating up on Laguna Beach, so Jason, Talan and Cedric go surfing - giving Alex M. the chance for a flirtatious prank.
At the Winter Formal, you can only count on one thing for sure: the girls ask the guys to it.
Stephen plays the odds this year when he rolls into town and takes Kristin to dinner on Valentine's Day night, and then brings flowers and candy to LC the next day.
