I find Gautam's Character far removed from reality. How can a husband for say 30 yrs, who has supported Dr. K through her studies and her career, as well has fathered 3 kids, be so mean to her wife (and CVs also showed that they enjoyed a good husband/wife relationship) be suddenly so mean to her. He is not only mean to his own wife, but also a new DIL, who just came to his household because he and others in his family wanted her to be his son's wife and supported his son's almost throughout until his mom showed up. I agree most often than not, a son struggles to balance the relationship between his wife and his mother, but shouldn't we expect a little bit more from his character as a mature, experience and educated person who can balance his different relationships and maintain the needed decorum with his new DIL and his family.
For me, I am finding that CV is not balancing this character well. I guess the CV is aiming to show a rift between Dr. K and Gautam regarding Nandu in the future, but can't that be handled in a mature manner without literally destroying the very essence of the character….Just my POV…
