This seems like the way they are heading and I hope that Sai is the one who initiates the search and tells everyone to not lose hope ....buttttttt do you really think V will have a realization and relate it to Sais accident and feel guilty for not looking for her?
This is where I have a doubt that makers will screw up they won't show this part ....they will show V preoccupied with finding P ...which will give Sai the surety that VP are in love ...but I have a fear he won't have a realization about what happened with Sai and that accident and he didn't look for her ....makers will screw up here
The rest I can see happen but they don't know what they are doing with Vs character it's all screwed up
Virat’s realization will be internal. You have to see how he behaves post the accident. For example he will give vinu to sai right away after the reveal. Virat will never express in words. That will give away the story. He will show in his actions though 👍
