MJ is a very cunning and calculating man.. he went ahead to even demonstrate and see whether what happened with Rishi is a planned attack or not.. he dint naively take it as an accident..
This speaks a lot about this man.. the only person who can go to such extents to think is the person who himself is twisted.. now he will even try to find out who is playing with Rudra..
But one thing is that the family knows that MJ has done something wrong.. and this Diya is MJ gf only.. who is stuck on in this house.. and btw she is a gynaecologist.. which us again raising some questions...
