While Marissa does all she can to get to know her sister, Kaitlin just stirs up trouble for the gang as she prepares to celebrate her birthday.

Life goes on. Love goes on. But how can anyone focus on Valentine's Day after Johnny's tragedy? Well, maybe love and understanding are the medicines everyone needs now. Even so, nothing will be easy.

The kids receive their college acceptance and rejection letters, forcing them to make some life-altering decisions.

Some go East, some stay West for freshmen orientation weekends. Ryan and Marissa arrive at Berkeley, and Summer and student/poseur Seth visit Brown. Familiar faces also surface. Anna is at Brown. And doesn't Theresa's baby look like...Ryan?

A race to the bottom: Marissa's ties with Volchok may send her into substance-abuse free fall...but not before she gathers herself enough to save the Ryan-Sadie match. The Newport Group events turn violent.

When an old nemesis returns to Newport, Ryan gets caught up in helping her, causing a rift between him and Sadie.
