mujhe lagtha hai while deva doing pooja he will be getting flashbacks of them but he can not get up as he it's not a good sign.
After watching the new promo I guess Tara will leave the decision on Deva and Deva will let her go.
Then he will be heartbroken and his mother will make him understand to bring Tara back to home.kal hi bataya na uski maa ka faisla akhri faisla so he ll go for search to find Tara.
I think he won't be able to find her and she will come back as Maid.
As soon as the pooja ends deva rushed to his room. He changes his cloths and leave and will be sad that he did was unable to express himself. He must be expecting tara to understand him and stay with him. But since she left he will go behind her to fight but he can not see her anywhere.
But as you said maid bankar ayegi and her ms will play major role in deva identifying her in the crowd.
