Makers always do that cringe of playing BGMs and doing slow mo for 2 couples at same time. Earlier it was Sai V, VP. Now its Sai V and SaiYa. This is their fav trope. Earlier they showed Sai or P in turns watching from afar and being affected seeing V with the other. Now it'll be Satya and V both at various points looking uncomfortable or moping. Satya will be uncomfortable seeing Sai with V and kids knowing they are technically a family - biological one. But V will now burn seeing SaiYa and kids. Maza ayega to see him pay for what he put Sai through.
the look of Sai in the episode is only of being emotional and happy. Theres absolutely nothing soft or romantic to V that I perceived. She's still giving him regard as father to kids in that she told Vinu that V did try to search for P for his sake and V loves Vinu, cares for him. She won't poison kids against V. She knows how to handle Vinu. And now Vinu finally is turning to Sai for comfort and love.
V clearly was wanting Sai to say NO to Vinus request even though he knows Sai IS HIS AAI. For real. Still he had the audacity to look at Sai as if challenging her to say yes. Sai seems to have hardly acknowledged him though. He even essentially tells as he is handing pen that he doesn't approve but its for Vinu and she doesn't even react. Simply takes pen and happily signs.
This is Sai's moment. Long awaited. To be aai to her son. V can go to hell..
Now that P is gone, the drama quotient will be about Sai still being in Vs life through Vinu and V dealing with SaiYa romance blooming
And Amba BK conflict will keep the equations between both families strained.
But I'm confident that Ayesha will never make Sai V scenes cringe like NB did with VP. She'll do whats asked of her by makers but her spouse is Satya and Ayesha knows her character graph. Sai will maintain boundaries and Ayesha will show some degree of discomfort with both men. V because he's no longer her husband and Satya because it'll be a while before she "loves" him as her husband. So she's not gonna be comfortable with either man but she'll fulfil her obligations as bahu, wife and mother to Satya and tolerate V for sake of kids.
I don't worry for SaiRat cringe because
1. Ayesha is much more comfortable with Harshu than she is with NB.
2. NB has his own inhibitions and reservations and can never let go of social distancing.
