Any of these are possible. The CVs might even show ALL of these storylines, haha!
I just hope the CVs don't opt for DD's second marriage. Of course everyone deserves to find happiness again but her second chance was with Shiv. But the CVs killed him off in a terrible manner. Getting her married off again wouldn't work for me at least.
But after SidNi marriage I think Sid and Roshni will be sucked into family issues and squabbles!
