@Albut1, You have summed up almost everything I wanted to say.
I would also like to mention about Arpita's kangans...I actually find that creepier than the pictures. Its like Aarti is carrying a part of Arpita with her. Isn't that terrible? Not now, but when she falls in love with Yash, and when she begins to hope to be loved back in return, how heartbreaking would it be for her, if everytime Arpita's kangan jingled on her hands, Yash searched for his lost wife...and even after Yash falls in love with Aarti, that kangan on Aarti's hands would be like a constant reminder of arpita, for both of them! Thats dreadful! It might actually make coming out of the guilt even harder for Yash!
The kangan has to go, seriously, along with the pics! I want Aarti to create new memories in Yash's life, and not be a part of someone else's memory! Similarly Yash has to create new hopes and expectations and memories in Aarti's heart to erase the bitter Prashant related ones.
But that kangan has to go, seriously! I don't know how...but it has to!
