Oh sarcasm .....
Anyways.. objectively speaking ,the reason for mohini hating prerna is deep rooted and never addressed.neither by her husband nor her dear son...prerna is thopofied on her..it is getting messier and messier because nobody is ready to talk about it..rather just force their opinions on others.. ....mohini for a short while accepted prerna when she saw her saving anuraga life.....suddenly what happened that she switched sides again? Post bajaj anurag went on a self destructive spree all because of prerna not telling him the truth ..all that prerna has brought to anurag , in mohini s pov;is misery and pain . She is unable to see that in order to save anurag from prerna she is pushing him towards komo forcefully who will ruin them...(right now she doesnt know sona is komo) ..if given a chance prerna will win over mohini ..for that her husband and her son have a do a lot of ground work and not order her to accept prerna...
if molly thinks marriage is a joke ,its different...they consider sona as anurags wife and she is living with him under one roof ..what about that ? Anurags memory should come back then what?
Now for the slap things can be sorted without the slap but just to dramatize everything they just show it ...Idc for abusing n all....two mature adults indulging in slapping is not done.. although they could have done without it , may be it was necessary to rile up mohini further and make her turn totally evil..of course nothing will be sorted out this way...
