well, we all know karan was no prefect person, he pulled alot of stuff but at the end , he saw the goodness in tulsi.
same in mathan, he saw the situation, acted without thinking and then realized actions spke loudr than words and vola. im soo proud of him. great job matha. im gonna be so mad if its some scheme but either way, the scne of mathan and nandani was very touching
