When datta realized his love for nakku he wants to stop her. He holding her hand was the beginning. He keeps on watching her now and then and thinks about cheerful nakk and ruthless behavior during the marriage and how she saves his life and he become restless. When he brought her a tea he understands that she will drink the tea after he drink the tea and he made a first sip.
He never believes in any strangers. When samla approach him and say that vital god will give whatever you want {now what he want is nakku} he would do any think for that. And she also said aapki Jodi salamaath reha {he definitely want that} he dint even hesitate ask bajji to stop the car. This show how he really wants nakku. And he followed her.
After nakku get kidnapped he will be broken-down. I think this the datta Dukhoon ki aandhi!
I think this time he cry out loud for nakuu. During marriage only his room looks like thunder struck. But full PN will look like thunder struck. That why they are sincerely decorating the house.
And datta will throw our beloved kalavathi into trash for try to stop him. No one will able to stand against him.
