Issue here isn't Sai's marriage to Satya. It's the way they are getting in there. Before talking to Satya's family, she should have talked to savi first. Relationship where both partners have baggage should have been dealt with more sensitivity
Even I am against Saiya marriage as of now. There are two reasons. One is Savi and second Sai herself. Satya is in love with Girija but she is dead. Sai is in love with Virat and he is very much present in her life.
If Sai turns a blind eye to V's negative traits and mistakes the way V does of Pakhi's, I prefer Sai going back to Virat than marrying Satya or any other guy. Fix Vinu and give Savi her happy family and spend the life with your one true love. Virat gave enough reasons for Sai to move on with/without Vinu. If she is still stuck on Virat, might as well get back with him.
I don't mind the order. Meet Satya's family and tell them the truth. If they accept Savi, go ahead. If they don't, drop the idea.
Get Savi out of CN. As long as Savi is in CN, V will pull her in other direction and the poor kid will be sandwiched. Tell her about Satya and the new dynamic. Savi will not be comfortable but gently nudge her. Make her meet Satya and his family. See if they are welcoming and Savi is atleast responding. It will take time but can work provided Sai herself truly wants to move on and not just for the sake of showing off to Virat or making Vinu happy.
