In the above link looks like Maai has insulted Antara in some way and Satya has exploded with anger and started saying some pretty nasty things, I believe he says at some point that he would kill her if she wasnt his mother, and I was better off being an orphan rather than having you as a mother (not perfect translations but I tried 😊) Then typically Raghu steps in to defend his Maai (😡) and Satya tells him off too and calls him a "nauker" or servant at some point 😕...basically looks like this drama is going to go on for a while...

In the above link looks like Antara's mum will find out that her husband is dead and that Antara has been hiding it from her and this will obviously cause for her mental condition to deteriorate even more and more tension for Antara...I'm really hoping that Raghu jumps in here and helps Antara's mum deal with everything as a start for his redemption...
