No matter how much she had manipulated and suppressed Ariana, that girl had not reached the breaking point yet. The fact that she fought back with her today was enough to show the fangs that Ari was hiding until now. If that girl even got wind of the fact that her destiny had been decided by her and that such a cruel one.
Mrs Harlow was certain that Ari would fight back with everything in her hands. They could never let her know of this fact, not to mention the Serpents also told her that their existence couldn't be found by the police department. The fact that they were working in the Lonest City was muddled and covered by many of the higher officials and influential people.
If the news was leaked and that too because of her, then Mrs Harlow was worried that she would be shot dead without a single question.
