So other possibilities in my opinion would be...
a) Just mentioning of Suhani shall happen in the upcoming Holi sequence, which will bring back bitter memories and whatever little cordial relationship Nachiket and Ragini shared during the wedding will all evaporate into thin air.
b) Shaadi will happen with both stealing glances of each other and khamoshiyan and judaai playing in the background. A heart touching vidaai speech and so on.
c) Eventually Neil goes back with his champa and chameli to US. Of course after making Ragini feel guilty about moving on in life with Mr.Confusion. So we are back to square one plus a fake pati now as an update on relationship status.
d) Ideally kids are to bring the parents back together as per show crux, Nishi did and looks like she might just bring them back together again for some odd reasons...the doting father will come to rescue and they meet again. 😳
This I think will go on...eventually solving all problems and misunderstandings. Amidst all this we might just find Shilpa preggers with Ranbir's kid (after what we saw yesterday, highly possible. Balaji women are apparently fertile and kicking 😆) and Arav coming to the rescue.
All in all I do see Dr.Neil returning wapas to vides.😆
