Yeah. Spoiler
Unfortunately, the empress will plot a marriage for her with Carcel’s younger brother in order to save Escalante from the emperor’s demand that they prove their loyalty. This will cause an uproar in the Escalante household because not only does Miguel, Carcel’s younger brother hate her, his fiancée had just recently died. However, the father wanted to go along with the engagement so that Carcel doesn’t have to part in a war where everyone said he will die. Miguel hates Dolores because she used to treat his fiancée unkindly.
Dolores’s mother is a married countess. Basically the emperor slept with a married woman and got her pregnant. Her mother is still married to the count and her biological family refused to raise Dolores so the empress decided to adopt her and raise her but didn’t allow her to take the imperial family name.
Spoiler
Fortunately, Carcel decides he would rather risk going to war to prove Escalante family’s loyalty than for his younger brother to enter a loveless marriage when he didn’t need to especially since he’s not the heir but the second child. It’s normally the heir who has to marry politically. Younger brothers get more leeway to marry for love. Carcel also stated that he wants his younger brother to marry a woman he loves.

Guys any spoilers on Dolores???
