Taylor eagerly prepares for her first real birthday celebration, but she frets over the fact that Ryan has still not told her he loves her. Even more concerning is the fact that she has secretly applied to and been accepted at Berkeley, the same school Ryan is going to attend. Summer helps Taylor come up with a plan to help Ryan express his feelings. Meanwhile, Kaitlin misbehaves outrageously as a reaction to Julie dating Frank (guest star Kevin Sorbo), and Julie finds out there’s more than just the usual Cooper rebelliousness behind Kaitlin’s actions. Kirsten deals with more than her share of catty Newport women when she joins a yoga class. Summer wishes Seth were passionately interested in something, the way she is about the environment. And a powerful earthquake shakes Newport Beach.
