I have not been following the shoe properly for last couple of weeks since the pregnancy drama started so I don't fully know the story about the watch and the watch owner that Sampada seems to know. If you can explain, that would be great. All I know from WU is that he's connected fo Rachit's murder. So new entry seems to be connected to Rachit and has some dhushmani with KalMa but I'm 100% sure he's NOT interested in marrying Kalyani. Only worry is that AS might want Kalyani to marry him and completely separate her from Malhar.
Kalayani enquires mastani bai about who called her from this house as rachit. Mastani bai says she doesn't know but she has an evidence. She takes kalayni to a room where a wooden box was burning mastani worriedly dozes of the for with her hands opens the box with difficulty and hands over kalayni a watch.
( Later it was understood that atharva burned his hands so that malhar doent match mastanis finger prints with those on the almirah that had rachits dead body)
Later own kalayni searches malhar to say the truth from the beginning like from the rachits blackmail kaand so she was having the watch in her hand. Meanwhile sampu comes to taunt her and that time she saw the watch she panicks takes the watch from her hand and runs away. Kalayni is convinced that it was sampda after knowing the truth from malathi used some artists to blackmail her in the name of rachit ( because kallu doent know from when on sampu knows the malti truth and that it is as and not sampu who knows the truth).
