The only three words that kept ringing in my ears through out today's episode were: Madhu - Tum theek ho?
Today, that was the only concern Sultan had. He was only concerned for Madhu. When he asked her this for the very first time, she could have answered, but she didn't. She didn't, because she is of course not okay.
He repeatedly asked this question, till Madhu finally answered in the affirmative.
He didn't believe her even then. He let her go only because Madhu's eyes pleaded with him. They communicated through their eyes. He simply asked her to call him if she was in danger. He let her go because it was her wish, even if he didn't agree with her.
And here again, we see the contrast between the two men. RK kept hurting Madhu by holding her hand tightly. Sultan let go of her, because she wanted it. Once again RK forced, and Sultan ceased.
Nothing escaped him today. He let her go, but he is watching. He is Madhu's guardian angel😊
