Awesome Episode!!
Madhu opened up to Sultan, only to retract again. But Sultan understood her pain without her having to spell it out. He understood that she is hurting because she is lying to everybody. He understood that she is hurting because she has lied to her mother. He understood that it cannot be a small matter.
He did not force her to tell it to him, since he realized that that would make her uncomfortable. He simply advised her to go and tell the truth to her mom, for this was the only way she could maintain her sanity.
The relationship that didn't have a name till date got one today. He will always be looking out for her. She is safe with him - her "only" friend, her protector, her guardian angel!
