Have a feeling he will apologize and ask her to return but she will refuse because she told him once before that she would not go back if he misunderstood her again. She left on a high note, pride intact, so no reason to go back...
He will work on parents to convince her, and perhaps they and Gunjan will; she will go back (either to get her job back or talk to Dadi), when he will confess under the influence of adrenalin (would this be a first??!). Will probably happen on Friday, and will dramatically stop at the confession so we will be on edge all weekend wondering if R heard or not, if she did, how will she reply etc.
If she does hear, would that make her not want to work with KT? How will we get to second base?
