Based on yesterday's episode it looked like that he holds Survi responsible for his mother's condition.
I think Tai must have orchestrated something and Lata must be her victim. She placed the blame on Survi and convinced Kartik. She then scared survi and her dad to disappear from there, which must have cemented Kartik's belief. We will find out as show goes on. No reason to go back😆
Yeah that is essentially it 😆
