I doubt the surrogacy track will happen, don’t think the actors are ready to be parents onscreen. Babies are born in Kshows when they have run out of ideas and a big leap is going to happen.
Rishabh will not step into the triangle as long as Preeran marriage exists and he is married to Sherlyn.
Kareena Bua hinted at the future track when she warned Shrishti to stay away from Rishabh. She mentioned how emotionally vulnerable Rishabh was having lost the baby and he might get attracted to anyone who gives him emotional strength. It seemed odd to me as Rishabh is kuch bhi ho Rishta nibhana hai types.
But with Karan finding out about the no pregnancy, Sonakshi’s marriage definitely not happening and her moving to Luthra house, Preeta in self sacrificing mode, Rishabh will find himself in the same situation post Preeran ‘s both marriages trying to keep them together.
The best thing about the possibility of this track is Sherlyn will smartly figure out that as long as Preeran are married, she has an actual chance of making her marriage with Rishabh work and for that as much as she hates Preeta she has to support Rishabh’s efforts in keeping Preeran together.
Prithvi the equally smarter one will also figure out that with Sherlyn out of his life, and an easy to manipulate Krithika there is high possibility of Preetaji ka Prithvi happening and will work to break up Preeran marriage.
All this assuming once Sonakshi is in Luthra mansion, she does not fall for Rishabh. Then it is going to be a completely different story.
Hope they wrap the not happening marriage soon and bring Rishabh & Prithvi back.
