Finn growled, "None of this will save you from Dahlia! Hounding me will get you nowhere! You're better off getting rid of that baby while you still can, while she still hasn't found her! Let her go quietly in her sleep and she will be free. Keep her, and you risk hell raining down upon us."
"What does it matter to you?! It's not like you're going to be here protecting my daughter. You don't give a damn about her! Dahlia isn't going to do shit to you."
"My mother filled my head with the terror of what would happen to all of us if that child lived. You are all too ignorant to–"
"It's not exactly ignorant if we're trying to find out more and work around it, is it? It doesn't even concern you, Finn, not really. Not unless you wished to help, if it might mean finding your sister."
He narrowed his eyes. "What do you mean?"
"If you claim Dahlia is alive, isn't there a chance Freya could be, too? Perhaps she is waiting to be found, waiting to be rescued. I know for a fact I'm not letting anyone take my daughter from me. And if you had any sense you'd be looking for an alliance to take that chance to retrieve Freya rather than upholding some ridiculous desire to commit infanticide against someone in your family. It was always said that you were the most moral of your siblings, but I see no moral man in that chair, Finn. I see a coward. A man who would let his mother do her wicked will because he's bitter and never had the guts to stand up to his siblings, to walk away when he had the chance. I see a murderer. A brother who would slay his own kin, an uncle who would slit the throat of his niece. You are not dull, Finn, no, far from it, you are a miserable excuse of a man and I am horrified and embarrassed to have any relation to you."
She leaned over him. "Now, you can either tell me more and use your bitching in a productive way, or I will shove you back into that coffin because no one is going to be here making threats against my daughter. If you continue to try and hurt her, if you even think or fantasize about ending her life to save your own skin– as if you even deserve salvation– I will make you wish you never left that coffin in Mystic Falls, I will make you yearn for the days you were daggered and trapped in your own mind because when I leave you imprisoned in my mind, in my evil little world where all thieves and murderers and rapists get their sentences read out by a nightmare, you will beg me for forgiveness and I will grant you nothing."
He stared at her, perhaps thinking that her behavior only proved his point, that vampires were beasts, that the other members of his family deserved to be sent to their deaths like pigs about to be slaughtered. 
"Dahlia wanted Freya's power," he said darkly. "She will want the same with your daughter. She will take her free will, every drop of magic flowing in her. And with a tribrid witch... there is infinite magic to be acquired. Your child, born of a hybrid father with a werewolf mother, from the borrowed womb of a vampire, the blood of a powerful witch bloodline flowing through her veins, could destroy the world as we know it. Dahlia would be unstoppable. She will use her, she will break her, she will turn her into pure evil and the world will be reduced to ash if you're stupid enough to think you can stop her."
"I've not been defeated yet," said Yara, a cold gleam in her eyes. "And I won't be. Because anyone who comes for my children will wish for the mercy of hell and the devil. Anything will be preferable to what I do."
"And how, pray tell, are you going to stop that witch?"
"Anything and anyone can be killed. Even someone like Dahlia."
"She's unlike anything you've encountered."
"So we'll devise a plan that fits the person to kill the person. The more we learn about her, the more we stand to find out about her weaknesses and how they can be used against her. All spells have loopholes, all immortals have weak spots. If you've nothing else to offer, Finn, I'll go ahead and end the conversation now."
