I have always supported Arnal as Rabul, but since both Mrunal and Arjit have quit, have welcomed Vin as Purab since he is doing a wonderful job of it and this Disha also looks to be doing well.
But, for once I started thinking differently about Aalya. She is wrong in her stubbornness and rather childish as Abhi's sister who had been pampered when young by him, but what she did to the Arora family was way beyond childishness and deserves severe condemnation on all regards. But analyzing her character yesterday, seeing her feel so much about Purab, started feeling actually sorry for a second. Like, Abhi knows about her obsession about Purab, knows what she will do if anyone comes in between her and Purab, now knows also since he has got his memory back what she did to Pragya and that she was responsible for Bulbul's death and she had come to him just a day before and told she wanted to marry Purab and she will do whatever he says after that, should not Abhi have been more discreet in announcing Purab's marriage to Disha so openly. He knows that Purab does not love Disha but feels responsible for breaking her marriage, so, he must have been cautious in arranging the marriage ceremony. Now, Aalya who already has a villainous streak will go all out and become a dangerous killer element now and Abhi should have been prepared for any disaster approaching, looks like he will be a victim himself from the promo, though from a different enemy.
Abhi is always bent on arranging parties and functions in MM rather than analyzing all the mishaps that had been happening in his life. He knows Munni does not seem to like Pragya in character, but has done nothing to find out her background or question her deeply.
