Remember how Trishna asked Shammu to get help from RK for her film. Shammu might again do something which is against his character. Like his attempt to kill RK, he might this time might try to do what Trishna asked. Trishna is emotionally blackmailing him by comparing his love for Madhu and for her. So to make it equal Shammu might do something like this. So what will happen if Shammu asks RK for a film offer for Trishna. RK would be sure Madhu and her whole family is after his stardom and they are with him for their benefit. he won't believe anything Madhu says after this.
The other thing is Madhu's dialogue last night. Jokingly she said she is playing with RK on instruction of his rival. So I have a feeling Avinesh (new entry) will be RK's rival and a Superstar too. So maybe Dipali might get help from him OR this man might see Madhu and fell for her and might try to create misunderstandings or will make plans to make RK lose his position in film world. So this is also coming.
Another one is Madhu falling for Dipali trap. Dipali might tell Madhu RK knows Madhu loves her so it was she who made RK to test her love, so Madhu will feel kiss was also part of that test. Which would shatter Madhu and she won't believe RK's feelings are true for her.
In what way Ballu fits in I don't know what to think about it yet. Maybe he was released from jail now, so came to visit his jail friend and might decide to stay in Mumbai.
