"I don't think that I am," Sigma replied.
"You certainly have the aura of one… or the presence," Reina furrowed her eyebrows. "Still, it would be hard to find someone who would lie about that so easily… Most of us find pride in our blood."
"As I said, I don't think that I am… but I am looking for someone who might know the answer to that," Sigma replied while thinking that it would be a good idea if he told her a bit of truth to gain Reina's favor.
Since the group needed help to gather Intel and for other things, Sigma assumed that they needed to reveal a few things. Only the things that would leave them in a bad spot, though. They didn't know much about Reina, after all. Still, after revealing a few things about himself about Saria and how Kodro was involved in her kidnapping, Reina looked a bit compelled to share information with him.
