Aftering watching the promo & reading the tagline, they are trying to promote Seher as part of new twist in Sanam's life. They are not promoting Seher as a lead. Anyone else felt so?
All the supporting casts in season 2 are failure. Now Rahat Haya Faiz are also big disappointment for this CV needs an interesting supporting character & who could be better than bringing Surbhi Jyoti as Seher to this role. Gul & 4lions knows what viewers want from season 2 & they are constantly working to make season 2 better thats why they eliminated Naziya-Shaziya-Azhar-Asma's story from QH & in future they might wrap up RaHa-Faiz too. To back up all this they need a strong supporting character & of course Seher will also take revenge from Tanveer too.
Overall, i feel Seher as of now is a supporting character. Who will be of course different, intertesting, comic what not. In short a package. Seher's story will be part of Sanam's & SaHil's story. So no worries aboyt SaHil's story. Future of Seher's character may depend on audience acceptance and feedback. If there was any love track between her and Rehan there would be media article by now. In fact, there is no media speculation about that. I am interested to see Seher's entry, characterization & how Seher fits with current SaHil story.
PS... About Surbhi Jyoti playing Seher, we all know 4lions are having financial problems. Its expensive to bring any popular actress on board for Seher. It might be their strategy to cut the extra cost & SJ will play Seher even with lesser payment cause you will know how she feels about QH, Gul from her recent IVs with F32.
PPS... The interviewer in SJ IVs with Forum 32 told they read comments on their sites. So it will be great if you give your feedbacks over Rahat-Haya-Faiz track in F32 cause i am nowadays too busy to even visit F32.
