Yeah at this point, something must lead to Virat saying something that hurts Sai. May be deal marriage. Funny part is, Sai keeps saying it but when Virat says it she cannot take it :P So this could be it along with her misunderstanding Virat and Pakhi conversation (picked this up from other replies here)
Things that could push Virat off the edge
1. Lies Lies and Lies. Sai never lies according to him. This could be trigger.
2. Misunderstanding his feelings for Pakhi. This is something that puts him off terribly
3. Deal word from Sai again!! after all they will be sharing on Holi. This will make him feel betrayed.
Mostly 1 & 2 would lead him somewhere from where he could not turn back 😵
Personally for me I want him to just 'not stop her from leaving if she decides to go'. It will be more tolerable.
Also I dont want Sai to misunderstand him with Pakhi again! That guy has done enough already to make her see he has moved on. It is like misunderstanding his character. So I hope they dont show this. Just a hope though 😒
Virat is the only one Sai has now. He has to remember that at all times! He should not lose that protectiveness for her.
