"Was it an illusion? Did we just get tricked?"
"Unforgivable!"
Corson showed himself, unscathed and somehow different than before. The awkward vibe surrounding him disappeared and only superiority remained. Expressing how they felt after being fooled into thinking they taught Corson a lesson does not seem to bother the demon.
"Truly heartbreaking. The sight of you as a whole prick my chest with pain."
Instead of being grateful for Corson's kind and thoughtful words, the conjoined twins took his remark as something insulting. For them, they do not need sympathy or empathy from people because they make sure to give enough love to each other as possible. They would complement their skill as one and always erase the negative thoughts from each other's minds.
"Silence, fool! Your words amount to nothing! We have no need for facade and shallow sympathy!"
