You know what I would think would be fun. Seher enters the picture. She and Sanam meet, and after sometime they have a sweet reunion.
Seher will bring the fun. She is going to secretly torture Tanu and Raziya. How? If SAHIL have not admitted their love etc... Seher will be the catalyst.
Picture this scene...
Seher walks seductively over to Aahil.
Asks Sanam, " Who is this piece of delicious specimen?"
Sanam in shock answers, " My husband, Aahil."
Seher replies, " Wow! Your nights are probably a lot more active than mine. With him on my bed every night, I would definitely not be sleeping. Good job sis."
When they are alone Sanam tells Seher it's not that kind of marriage. Seher tells her she really thought she saw love between them and she knows she can't be wrong. Seher decides to secretly set up SAHIL. She probably causes things to happen, to ensure SAHIl are alone. She probably arranges a romantic candle light dinner, bubbles in the tub.. etc... and lock them in the room. She could be the dilshad of the future. Just like Dilshad forced Zoya/Asad first marriage on Asad as she knew his feelings for Zoya and would not make the decision on his own.. so will Seher force romantic occasions on the couple as they probably would not make the move on their own..
