I feel that scene was a glimpse of future track of our show. Somewhere I feel Sanjay is connected to Mehak's parents accident wherein she lost her parents. But I'm not sure about it because we really had little knowledge about this Sanjay. Also; Svetlana; KD Shouri and Sanjay the trio will going to create a lot of problems for MehRya. Well, what happened to KD's contract thing? They are not showing this right now. I can imagine after MehRya's marriage there will be a lot of misunderstandings between Shaurie and Mehak because of the trio. But it is far for now. Let's see first how Shaurie will impress his love? Lots of drama is coming for us to watch. Also, Sanjay is gonna make his entry soon(probably next week) and I am sure Svetlana and Sanjay these two evil will join hands with KD.
Btw I am assuming by backstabbing; Svetlana meant to be herself. If it will be Mehak or Rajeev then poor Shaurie will be so hurt. If his love Mehak will betray him, he will be heartbroken. If it will be Rajeev, how can he? He is a very good friend of Shaurie and he trusts him. He will feel hurt. Can't see my Shaurie in pain.
