She could be a no-nonsense matriarch who comes from humble origins, and who helps her son (Raam's dad) build a successful business (but was not able to give him sufficient morals not to have a secret family on the side).
She would see through the shenanigans of Kaykei and Shakuni and the other rascals, recognize the true worth of Priya, and lovingly accept her as her grand-bahu. She would warn Priya about the scallywags and get her to promise to protect Raam from their evil intentions, but also never to reveal their true colours to Raam otherwise he shatters.
She would tell Karthik not to hesitate to do what's required to rein in Nutzilla and come to her if Raam creates new problems.
Oh well, maybe its too much to expect.
Thoughts anyone?
