Ideally, JW goes back to being RB, sees Bani and the kid, misunderstandings galore, and slowly begins to understand what Jigs has done to him. Mind you I think regardless of the misunderstandings, cracks, etc. to some extent, Bani deserves some punishment coz the cracks happened because she hid things from JW. I still don't understand what the big deal in telling him Daksh was her BIL would be but that's the foundation of the breakup so no point going there.
But there should only be misunderstandings, no marriages. The main thing though is that it shouldn't drag on and on. If they tightened the storylines and resolved their twists and turns within a couple of weeks, people would regain their interest but if they use four months like the last time, they should just take KS off the air...
