They have consummated. The scene in the night ended at a mutual hug, and in the morning Khushi's dupatta was lying in the middle of the bed, and they both stared at each other with love, and Arnav was advancing towards Khushi, who did not bother to get her dupatta on, until they were interrupted by Nani (who was the only one left to interrupt them). Then Arnav left saying their discussion wasn't finished.
I think their discussion will never be finished. The new entry of Dadi will create amither MU, and Khushi will find hetself pregnant and hearybroken.
Arnav has won today, in his goal to bring Khushi back to RM. I don't think he has won in love, it only seems like that.
My wuestion is , Khushi, why did you succumb so easily ?.
