One thing is for sure, Sai is the "Heroine", if Virat will be happy with Patra, then they will bring new "Hero" opposite Sai, and Virat will become official "Villian" and there's no two cents about it, and abhi Jo uski harkatein hai like CA, revenge and all, it's no less than villian tendencies, let's see what makers will turn him......
But the thing is logically he can't stay happy with Patralekha, if he wants Savi, coz wouldn't the kid question him seeing him being happy with another Woman while her mom is suffering, what will he answer and what revenge he gonna take from Sai, coz taking revenge from Sai means directly/indirectly hurting his own child, coz Savi will be affected too along with Sai......
Having said that I still feel it's all bcoz of trp race, they want #1 position and that's why doing all sort of tactics......
