Diana better not be leaving for London. Will they call the show 'Cinco Hermanas' then? Celia needs her support, because quite frankly I can't see Petra fully supporting Celia. They might bond over the 'we both have to keep our (respective) loves a secret', but Aurora will be less than thrilled about it - more drama on the horizon.
And speaking of secrets, I can see Petra acting all hurt because Celia said there wouldn't be any secrets between them, now that they are amigas again, and while Petra spilled her guts about Bernardo, Celia kept the relationship with Aurora a secret.
