I agree, Gopi knew how kokila will react if she found out that her wishes or demand has not been followed through and despite that she went opposite to her mother in laws demands to hand over the jwellery to Rashi. If i were Kokila i would be hurt too but i wouldnt punish Gopi in that way. I guess Kokila wants to have the control as she never had that before with Hetal and the house so why not try on Gopi as Gopi is a mouse. In a positive note i think it would do good for Gopi to become more responsible rather than give her things away and live for others hapinesss.
I was really mad at Gopi as in that Episode she hardly spke a word, she walks , talks and does things slowly, she needs to pick up things very quick.
The Kitchen Episode--- Why didnt Gopi let Rashi do the cooking, why does she has to do all alone.
