Although he was being pushed into a corner, Blond didn't seem fazed in the least. He just stayed sitting across Red with the same expression on his face as if what Red asks of him was just something casual. However, unknown to everyone, Blond was doing all he could to not let his guard down at the mind battles he was having with Red. After all, a tiny slip up would cause him to reveal all his cards, not only to Red but to everyone in the group.
"The Plains? What do you need to know?" Blond asked him although he already had a vague idea that Red already knew about it.
I mean, if he didn't know, he wouldn't have called it the Plains just like how Head Cipher coined it. Whoever's behind him must be close to Head Cipher as well. Blond thought to himself as he kept up the pretense of knowing the bare minimum about the Plains.
