Ok when Linda came, we found out that Rusty was evil and wanted to get revenge. However, we found out that Rusty isn't really evil and not out to get the Deol family because she realized that they love her very much and she does too.
Linda's mom finds out and doesn't like it very much. Samay is introduced as Randhir's best friend's son. He is from Canada and came to India for a business deal. He sees Rusty and is smitten by her. Rusty and Samay get off at the wrong foot and Rusty hates him because he openly said that he wished she would sleep with him. Therefore, Rusty hates him. Samay on the other hand, wants to get Rusty and realizes that he loves her a lot. During this, Samay destroys that Deol family and their business until they are reduced to begging on the street.
Meanwhile, Linda dies due to being drunk and Samay blackmails Rusty that if she doesn't marry him, he would show the clip on his cellphone that her dad killed Linda. Randhir was there at the time when Linda accidently fell off the balcony, and Samay captured their meeting and her fall. Samay cropped the images making it look like Randhir pushed her.
Rusty as a dutiful daughter tries to protect her father's image and agrees to marry him.
Randhir meanwhile hates Samay as well for ruining her business. When Randhir finds out that Rusty is going to marry Samay, he is furious and throws her out of the house. Rusty has no where to go and Samay takes her with her.
That's all happened. And yes, yesterday we saw that Samay's family came to India and Randhir is a cab driver.
