My shot -
DK is going to do some serious thinking about what Suhas has said. He will also observe how much at ease Disha is with V but never with him. Show some flashbacks.
Gargi will come to know DK has put a stop to the dodgy character she was doing business with. She and Pori will be making life difficult for Disha with their usual snide remarks/actions and she in turn will be tense and short with DK.
Disha once said to DK, 'You don't know what sacrificing for people you love means' - I think they were talking about Disha giving up Inder for Rano. So although he really really desperately loves her, he will decide to let her go because he believes that is where her happiness lies. Will also not mention Suhas's conversation with him to Disha.
By the end of the week, I see him signing the divorce papers....... ðŸ˜
