According to spoiler,Yuvraj and Bhavna marriages preparation is on the way so If dadi is faking her memory loss and doing this purposely then from my side scolding words for her and yuck yuck to her evil mind.Even in her memory loss she is sweet to rags only doing emotional drama to make suhani dance on her tune indirectly.
If c is not faking and really she has partial memory loss,,then OK(I highly doubt the later one)...but seriously if she doing purposely I mean In this age of Yuvraj and Bhavna,she really want to commit big SIN.Dadi is not only evil but sinner too.Even god and holy water couldnt wash off her deeds.
Lets c how the current story unfold in near future
