Gandalf noticed how somber his sister looked, he abandoned his sword on top of the table and walked to her. No matter how much arrogant Gandalf may look, or like a man who doesn't care, his higher calling and priority was his sister. When Aryan is sad, spoken badly to or even mocked by her appearance ─ those people never survived long to tell more tales.
"What is it sister?" asked Gandalf holding his sister's shoulders. "I promise I will make it up to you. I know it's hard being… this kind of a person who is not you. Imagine all this kingdom under our fingers, how father will be so proud of us."
"What will happen to Prince Amabel and the queen?"
"They will have to die."
"Argh." Aryan sighed softly. "Why do we have to murder innocent people?"
"You will not have to do anything nor would I have you fight this war. After the wedding, I can send you to the Liberty Cities with Olivia until it's all done."
