I feel Ragav will accept poo for revenge and Kalpi finds out and stops the wedding at the last minute phoo kamla maa will think Kalpi did it for her own self and Ragav will be angry with her too. I see more scope in this track. Or maybe kalpi and saami swap in a way that Ragav end up marrying kalpi and than of course kalpi family will hate her and ragav will be in rage too as she spoiled his plan. Something along those lines.
