I think Eklavya will kill Tanya\
How:
Tanya will not believe that Manthan raped
She still believes it's Eklavya
She will try to get justice for Manthan and will come to know that he is evil. Tanya will also try to unvil that Eklavya is Evil and She will come to some of his plans
To save his plans he will kill her and then he will tell Bhoomi that one of the Virani's have killed her (most likely to be Tulsi, Karan, or Nandni)
Then Bhoomi will like to get revenge, and soon will find out that Eklavya have killed her.
and at the End (not shows end), Bhoomi will kill Eklavya. for killing her mother, who always cared for Bhoomi.
Bhoomi will be pregnant when she will go to jail for murder. Probably with Abhir's child, she will not turn good so quickly. (she will be like Nandni, went to jail when pregnant)
