My reasoning for saying so :
1. Doctor confirmed that he was forced to give a fake report about Tara's pregnancy. So Aarohi/Tara continuous rant even in today's episode about pregnancy and Bachcha is of no use.
2. To prove to Deep that she is Tara & not Aarohi, today Aarohi has shown a video to Deep. Whatever little I could understand from that video, Aarohi is telling the nurse that Tara & Deep's child should not see light of this world.Yani ki Aarohi in disguise of Tara wants to prove that Aarohi is alive and wants to harm their to be born child. I don't think Deep will buy this.
3. And the most important thing...when Deep entered the room next morning, he was very emotional and had tears in his eyes. Was it for Tara & her pregnancy. In my opinion...NO. It was out of happiness that Aarohi is alive and she is staying in the same house.
4. The very fact that Deep agreed to take Aarohi in disguise of Tara to take her to Nikku confirms that he has recognized her. Was he taking Tara to Nikku. NO. He wanted to give happiness to Aarohi by taking her to Nikku.
I strongly feel that Deep has recognized Aarohi. Now he is replaying his own game but this time in reverse direction.He will make everyone including Aarohi believe that the lady staying in the house is Tara. Aarohi is alive and is trying to destroy Raichand/Rajsingh family. He will make everyone believe that Tara who is hostage is Aarohi.
Real Aarohi will take advantage of this scenario and will succeed in her plan to put Deep behind the bar.
Hope I am not wrong.
BTW..I liked the twist in today's episode but could not understand that video thing properly.
