I feel this is another attempt to make Anmol look negative and make us all believe in Vasu's theory about Anmol.
It is not Anmol who did it, I think it was his friend, who was the organizer of the event painting competition who did this, as he knew Anmol's last name .
There was this scene where Anmol introduces Raagini and Tammy as his wife and daughter resp.,to his friend. So this friend who has no idea of Anmol's real story, assumed Anmol's daughter as Tamanna Anmol Sareen.
What do you guys think?
