Meanwhile, Courtney takes the next step with her secret boyfriend - and future stepbrother - and as their parents' wedding approaches, the pressure's on to reveal their relationship.

And with the boy who betrayed her but who could be the love of her life fighting for his own life, she might need the Diamond sisters more than ever.
