Yamen starts to build a deeper connection with Alana, while Caro gets to know Cormac a little better. Meanwhile, all the Islanders band together for Weston's rootin'-tootin' birthday, which is upstaged by the arrival of two new female Islanders.

Yamen and Weston cuddle up to Christen and Katrina, respectively, while Alana and Mallory spend an unromantic night in the Hideaway suite together. Then, after a comical competition empowers all the girls, each boy takes ultimate control at a recoupling ceremony that sends two Islanders packing.
