For that Chakor should have any problem with Imli,then Sooraj has to talk and clear it.
The MU she had only because of Vivaan's reports and it cleared and I don't think she is going to doubt Imli on anything and ask Sooraj to clear about it.
I'm not sure Ragini ever make a comeback to the show or become invisible like many other characters in the show,because if she came back,Imli's truth will come out,it will be against Imli and if ever she came back,they may even cover that part how she got escaped.
But at least with new election drama, I hope Sooraj and Chakor would get more screen space because Imli will not have much role in it.
