Aarvi was aware of how Aaron and others were trying to have patience just because she wanted to handle Leon. She knew that too well than anybody else.
But what will they do? Beat Leon? Was that enough? Or kill Leon? Then what would be the difference between Leon and them?
She wasn't killing Leon, doesn't mean that she was going to let him live peacefully. That doesn't mean she would watch if Leon goes out of control. If his actions threaten anyone's life around her, she would be the first one to get her hands coated in his blood.
Whatever she would do, she was going to make sure, Leon craves to die yet hard to die. She won't give him a chance of redemption by escaping anywhere. She will make his life a living hell while he will curse her day and night when she will live peacefully.
If whatever she does, fails to cool down her husband or brother or friends, she will let them have their way. Until that, Leon was only her prey.
