Some points are true in ur analysis. But I disagree that MJ will not harm Rudra. MJ is a narcissistic person and a control freak. To prove his sons GF is a gold digger he kissed her in elevator . He emotionally harmed him to show that he is right and Rudra was wrong regarding his GF. MJ is an abuser who abuses his wife manhandling her all the time. When Rishi wanted to marry Maya he slapped and locked him in a room. He can go to any extent if Rudra disagrees with his point and questions him to physically hurt him. He will do it when Rudra takes mayas side in this MB.
I agree that Mayas plan is not clear until now after the marriage. She was brutally abused by MJ and she has PTSD from the trauma she went through . Her plan was to kill both Rudra and Rishi , later disappear . It was Rudra who brought her home and made her stand in front of MJ . She will slowly start getting stronger with Rudras love to fight MJ . Give her a slack . She will start fighting head on with MJ
