Another interesting episode . And reading your discussions her was no less interesting . 
Salar is trying to secure Sitara's future using his power and money. She knows her family fears him and he is happy with it. He used Sitara's sentences about how mid class families fear their son in laws.. but why didn't he use her latest sentences? She told him : can you return my family's respect and love for me? This is exactly what @Hatimoon kept pointing at.. which is that Salar didn't try to clear Sitara's name. I know none will believe him, but at least he should've tried.
Salar is too concerned about Sitara , he can't go away without making sure he can learn about her well being. That's why when she returned the mobile, he used his powerful card and sent it with a car to her family, so she has no other option but to accept it. But he thinks that her uncle us greedy, which Sitara couldn't accept it, and had to return his gifts in a rude way.. by hurting Salar physically this time (which broke my heart
).
I feel like now I understand Sitara's actions much better. Seeing the look in her eyes while she was leaving the house to meet Salar was heartbreaking. None of her family cares for her. It is very hurting to live in that atmosphere. 
Salman is very disgusting . And I felt scared that if Sitara marries him he'll use her as a money machine. He won't hesitate from sending her to Salar to get him money or work. 
I can see this serial runs for many weeks.
