There will be something with Gauri and since they are mentioning marriage it's huge possibility she will be chosen to be Bride 50.
Neither one couple in Udaan went trough life without problems. Starting from KN-Teju, Ranjana-Manohar, KN-Ranjana, and not to mention Sukor and Imvaan. Even Bhuvan-Kasturi were shown having problems after leap when Bhuvan suported Imli's work for KN and Suraj and Kasturi didn't. Altough it was not payed lot of attention. There will be hardships for Chagan-Gauri and it's better if they finish before marriage. Later on they can be shown as good support to each other and Sukor too.
Hopefully the twist with Gauri can be to show Suraj on Chakor's side or Suraj going against Hyar. There is reason why Sukor meet for the first time on that marriage night. There is reason why next bride will be the jubilant 50. There is reason why election track is brought up, and I hope that it's to give time to Sukor relationship to progress before things go as they were before(selling brides). There is reason why Chagan was hero last Wednesday, so Suraj can be hero when it comes to one Chagan loves. I hope, I so hope it will be like this.
