Rue pursues a new dangerous business venture as she sinks deep into her addiction, largely caused by her guilt-ridden new friend Eliott. Cassie struggles with her celibacy and starts to drift, while Lexi pours herself into mounting a school play. Nate is in full redemption, trying to redeem the mistakes of his father.
