I don't really get this point since she already gave a part of the haveli to Mri/Gau. So bringing back Jumkha is like spitting under the rain. Yes it's not the BEST decision but we can't forgot that there is feeling in both side : dhum and Jhumka.
Or do you think that she could turn evil in the futur beeing the "older bahu" ?
About Murli's face again i did not see anything special, everyone was looking perplex he even smiled at the end.
Ans Bharti ALWAYS looks down.
Murli's smile at the end was 'deja vu, deja recu" expression. I am waiting for him to find out that Bharti once again suggested that Damru get wed to Jhumka. Of course, he is out voted because everyone wants this. And when the day comes, with Murli, I will pop a champagne to enjoy Bharti's barbadi because of her blind trust of people's sweet words (as Murli said).
