It would be intriguing to see how Zareen's character turns out.
I was wondering: it might be possible that Zareen wanted to get rid of Azaan and not Kabir. After all, it WAS Azaan who was supposed to be on the site that day. Kabir went out of the way. His going wasnt planned. So it might be that Zareen's plan (for whatever reason she wanted to get rid of Azaan) backfired as Kabir died.
