Truth to be told, Olivia's suspicion was completely justified.
Earlier, when they went through the curtain in the master bedroom, they were transported into the bare luxurious room where Ozzie and Maureen were engaged in a fierce fight and surprisingly, the one they saw was not Maureen but the Madam of the Knox Family!
In other words, they witnessed Ozzie cornering Madam and bullying her!
Ji Yan was so shocked that he almost rushed forward to prevent Ozzie from killing her.
Fortunately, Olivia stopped him before he could do that. "Wait." She said in a solemn tone. "That is not Madam. Think about it, Madam and Master Luca have reunited and the one who occupied her body right now should be the black witch we have to defeat!"
Ji Yan was enlightened and almost broke out in cold sweat. He hit his forehead. "You're right! I almost forgot about that important fact!"
