Lovely post.
Seher's character has yet to come to the fore.She has the spunk of Zoya. But its a mask we are seeing right now.
Basically, Seher and Rehaan are characters, whom you will fall in love with instantly. They are like the noodles that they shared.
Sanam and Ahil grow on you and once bitten, you become their fan for life.
Sanam is the unsung hero, both in the serial as well as here in the forum.
As for Seher and Rehaan, till now there haven't been any romantic feel to their scenes. Seher tripped today but it didnt result in fall and eyelocks. They provide a good relief in otherwise heavy duty drama. Whether they have a story or not, time will tell.
I agree, Shehzaad needs to buck up when he is in one frame with Surbhi, especially comic scenes, though he has improved a lot.
And Rehaan is no Asad, no way. Totally agree with you there. If there is an Asad now, it is sanam and only her.
