As we saw in the yesterdays episode that Dadi hd taken Suhani to a store room so that she can bald Suhani's hair... Indirectly to humiliate Suhani being unable to conceive... thats her intention to puncture Suhani's happiness and break her relation to Yuvraj... Though the track isn't clear but it seems to be the same... Suhani is shown little broken down after knowing the reports... On the other hand Dadi is pampering Suhani, acting sweet like a sugar... She is playing very clever this time... She knows that directly she can't get rid of her so...playing sweet n in an indirect way...She can easily win Suhani's trust and love...So Dadi had a sudden hunger strike for great gran child..
Further I think today she will put the blame on Suhani for forcing her to do this crap...Or if not by this way then she will try for sympathy from everyone telling that she can't see Suhani in such pain so she tried this way... Being an old lady thirsty to become great granny.. Further more I think Dadi will fake of getting ill, bedridden... and cry for great gran... Indirectly forcing Suhani to leave Yuvraj and tell him to marry other girl...
