Guess I'm the only one unhappy at this development.
It's clear now that Canaria and Cesar will solve their misunderstanding and the true fight will be against the Emperor's decision of marrying him to Gracie. This avoid most of the conflict and leads quickly to a fluffy ending, since Miss Lancaster will be more interested in becoming Duchess.
I wanted a tougher route whereby Canaria broached to Cesar that she was ready to divorce him (in her mind, as per his wishes) to let him advance towards his goal. Then he'd be devastated, ask something like "So all of this was an act?" and there would be tears and separation. Canaria would then get her peaceful divorce and alimony, only to realise she missed Cesar after all, and the story would evolve with each going this way and that until they rediscovered their love, against all odds. It would be comedy gold, too, seeing Cesar go after Canaria in her new life.
Guess I like it when characters suffer a little more. These two are far too quick to go into each other's arms. After all, the title was supposed to mean surviving was the main goal. The way things go, it's too easy, she just had to be friendly and honest, and rely on the book to give her clues.
Still a good series, though. But I'm enjoying the comedy in Why are you doing this, Duke? more.
