I felt it was a major blooper in the script today when Shaan told Sunil that everything is going right because of Sam's re-entry into his life.
As Aditi pointed out in the DT, before going to his project presentation, way back in Aug, Shaan told Khanak that as long as she is with him, nothing bad will ever happen. Now to me that means Khanak is the good luck charm.
Now it's Sam?
Are the writers struggling to show how important Sam is to Shaan? They don't need to put her in the same place as Khanak. She can still be a very important friend.
