I agree u point by point . Yehi mein samjhana aur bolna chaha rahi thi! And for this Rachit ka koi naxalite record na vi ho toh vi chalega. His agengda can b a separate thing .Another extremely convenient aspect of this partial amnesia is that everyone will feel sorry for Madhuri. No one wants to get angry at a pretty lady who seems to vulnerable and helpless. And in this situation, when Anupriya gets extremely angry or defensive with Madhuri, she will be seen as the bad guy cause no one will remember all the humiliation she dealt with when Madhuri stole her husband.
Also, Kalyani is in a huge dilemma. With Madhuri's partial memory loss, she can't tell Madhuri the full story about anything nor can she get angry with her for the what she did to Anupriya. And though Madhuri wronged Anupriya, she loved Kalyani immensely. So Kalyani is stuck in a really hard place.
If this is a plan by Rachit, which is exactly where I think this is heading, then it is a brilliant plan. Cause Madhuri is the perfect trump card to separate her from Anupriya and even Malhar. I'm 1000% sure that over time she'll prefer Rachit to Malhar, especially not knowing the full story about their past. Cause from her perspective, Malhar is a "down grade" compared to "perfect" Rachit.
This is actually a pretty interesting track cause I have personally always wanted to see Malhar's and Anu's interactions with Madhuri. And Mahduri's opinion of Kalyani's new life.
