"So, in other words, you have no proof to prove that you are my sister, right?" Zach placed the dagger on the girl's neck and asked, "Tell me one reason to trust you?"
The girl looked into Zach's eyes without any fear and said, "You don't necessarily have to believe you. If you think I am lying, go ahead and r*pe or do whatever you want with your body. But I wonder how you would feel like after you learn that I was telling the truth and you r*ped your sister?"
Zach frowned his face and glared at the girl for a few seconds, seemingly trying to intimidate her into making her confess the truth.
"Alright, then, tell me your mother's name?" Zach asked.
"I can't say that."
"Why not? I know the names of all my mothers."
"No, you don't," the girl scoffed softly and said, "Do you really think father brought all his wives to his home in the human world?"
"..."
"Okay then, tell me your name."
"I can't say that either."
SIGH!
