Bela and Vish - Makers are giving mixed signals. 2/3 times they've show these two looking at each other, without hatred/jealousy/indifference. Even if they are working together, what's the need to marry Mahir/Yuvi. Revenge is possible without mrg too. So there is more than Ruhi's revenge.
What happened after Bela jumped into the river? That will be revealed later. But within minutes both baap-beti duo were back in mrg mandap, all decked up, as if nothing ever happened.
The wedding vows were indicative of what will happen in future. I wish Mahir was shown saying the vows too. (Btw, main aapka khayal hi nahin rakhoongi, aapko apne khayalon mein bhi rakhoongi was cutely funny 😆)
