If cvs change track & end naagin .story may go similar like jhumki ,where roli enters again .new character will be sid look alike after few epi real sid will be back coz when rashmi can't afford dress how she'l afford big lavish house for permanent for humshakal .
Another ,story may take u turn like shruti ..new character will turn sid at the end .
Guys story is all about sisters and their enemies .cvs won't seperate them so roli not going anywhere .sid body disappear like roli ( veeru naina story) .rosid will reunite but it'l take time ..
