Calidora's scheme has been haunting Evelyn's mind like a maggot to a carcass.
It was even worse knowing that Rex was still troubled by that incident, saying that they were lucky that he was weakened. Had he not weakened, the incident would have ended in tragedy instead, and she understands that this must be weighing down on him.
All due to the fear of losing more than he already lost.
Just the thought of killing those dear to him with his own claws must've been dreadful.
Evelyn could only massage her forehead as problems kept on arising no matter if it involved the whole world or only the greed of one person. It was also unsettling, the fact that the more she thought about Calidora's scheme, the more she found that it was flawless.
She twisted the situation so badly to her advantage.
Gaining Luna energy and managing to achieve a significant step in her relationship with Rex.
Her scheme managed to kill two birds at once.
