This week it's Maya

1) Maya was crying near Jaanvi and suddenly the Phase 1 Maya came back with that look and said I am sorry.

2)At last, the inspector said whoever did this, I salute him/her. After few minutes, some senior officer passed by and he saluted and right at that moment, Maya was also behind that senior officer.

My guess is split personality. In case Maya turn out to be the mastermind, I hope, by the end of the show, it revealed to be her split personality and that simple-sweet Maya live the life and get all the love that she deserve which was missing since her childhood.

Lastly, I would like to finish by saying that I didn't liked this behaviour of Arjun, he didn't tell anyone that he has told Jaanvi to write the letter, not Jaanvi herself. This was selfish/duffer on his part. He just let the blame be put on Maya's mother that easily. This make me doubt his love as well. For one moment, he stood against Vandana for Maya "mujhe dono mein se ek rishta todna hoga" and the next moment this...His character is confusing.
