I doubt. Looks like Nandini is SHOCKED seeing him. I think N-V now thinks their plan has worked to separate Raya, so they want the kaand to be at home in his absence. Later they can manipulate him like they always do.
But, you could be right too!
I think Nandini is shocked seeing Ram support Priya and Akki. Chances of Priya calling Ram are less, she is also guilty about using harsh words on him or it could be that Ram comes to meet Priya to understand why she talked about the deal all of sudden and he witnesses the kaand himself
