The only thing i see that she will believe the half-truth that DM will put out. I dont want to believe but in most shows that is what happens. However, this show is so unique and entirely different it would be really, really, really great if she did have doubts at first (after the initial shock) but she realize after all the things she has gone through with Raghu all their moments, Raghu himself, how he is and etc...That should make Antara realize their some gaps or loop-holes in what DM told her. She has to question it, because i feel like Antara character herself isn't someone that would just take something someone told her. She would question it, but then again she did readily jump and made assumptions about Raghu character in the beginning...but things have changed so she should have trust in Raghu character. If not, then this shows that Antara and Raghu's relationship has more maturation that it needs to undergoes.
