It seems he's built a bit of a rapport with Yash and although our sweet faced Yash didn't jnow Sid's true identity, he might help our hero make amends with Roshni. Yash will probably go to Mumbai and see that Roshni trully loves Sid and for her happiness he vows to help them get back together, thus helping Sid uncover Rajveer's ploys and sacrificing his love for Roshni.
It's obvious Sid needs new tactics and importantly more allies! Perhaps Yash is the one..
What do you think folks?
