Vance piped up, interjecting their discussion to ask questions, "Speaking of it, how on earth did you know about that? About Melva being the heir of the Moon Goddess? You are literally in a different world from hers. Where did you hear it from?"
His distrust towards Geneva seemed to be permanent. No matter what the witch did to prove herself innocent, Vance would turn a blind eye to it. He would still blame her for everything bad that happened when she was around.
Melva knew that Vance was being unreasonable. She could not justify his overly severe distrust towards Geneva even when it was obvious that the witch was helpless currently, locked inside the barrier created by Rosetta. Only Rosetta would be able to let Geneva in or out.
There was no reason for Vance to not trust Geneva. But still, he did not trust her. He kept making excuses if they tried to convince him that she would not be able to do anything to harm them.
