But why?
How does that help them to prove she is plotting against Abhi to destroy him?
Does Pragya and Daadi not remember Purab somewhere betrayed Aaliyah which triggerd her to grow into a psychotic obsessed person? Pragya's own sister Bulbul has taken Aaliyah's position in that sense. If anything Pragya should not rub salt to that wound Aaliyah still has raw. Because that will be destructive.
How come the same Pragya wanted to forgive her even when she tried to kill BB? Now she is just randomly bringing up Purab matter?
Let alone this being a sensitive issue, Pragya and Daadi later worry about Aaliyah further turning against Pragya over this. Of couse soon they might realize how she has already planned Pragya's murder. Pragya's luck or Abhi might save her from the killer but in anyways, I didn't see a point to taunt Aaliyah and even tell her Ronnie wouldn't want to marry her either.
Did Pragya forget her days where no one wanted to marry her now that she has a rockstar in love with her? What do Daadi and Pragya want to do to Aaliyah? Turn her into a real murderer or teach her a lesson? I don't see her learning any lesson here but she is only growing further into a monster.
