Aarvi understood the whole picture Dylan was in. She wasn't sure how much it was true or if he was faking everything just so he could help Leon play dirty against her like every time.
However, one thing was sure, Leon didn't know Dylan was helping her out in the ordeal three years back. She has to see the true color Dylan for Leon. If he was supporting Leon, she wanted him to be against him.
"Leon killed your parents." She tested if he was aware.
There was a pause in Dylan's movements, "I know." Dylan's voice sounded menacing when he stood by the hearth and lit it to destroy the pictures.
If Dylan wasn't acting, Aarvi discerned his aim wasn't just to get his sister. He was going to kill Leon soon after. He was stuck in the past without being able to move on or think about his own life.
So Dylan knew one of the secrets of Leon. Aarvi nodded to herself. "He also killed his parents."
