I am thinking that , going by the tracks shown till date, malini has tried each and every small medium tricks but all went in vain so now miscarriage is the last option for her. Be it fake or real pregnancy...she can use it against Imlie and I doubt this plan can be successful as writer's can't leave this point and make it went in vain also.... but the show has already lost its unique charm .. before malini turning psycho.. there was no villain (except Anu)...and still the story had many twist and turns... but now this show also following trends of each and every show running on tv these days...
