Bomb blast to kill RK and Madhu, Radha to escape to Mathura with Madhu

United in love, united in death' - thus will end the love story of RK (Vivian Dsena) and Madhu (Drashti Dhami) in Saurabh Tewari's Madhubala - Ek Ishq Ek Junoon on Colors.

Yes, the much-talked about twist which will lead the story to an 18 years leap will unfold this week.

The sad demise of RK's family will happen with a huge bomb blast in RK's mansion, just as the naming ceremony of his new-born daughter would be on.

So what will trigger the bomb blast?

As per the ongoing track, RK had agreed to star in a movie to be produced jointly by Harshvardhan (Arbaaz Ali Khan) and RK, which will also have Abhay Kapoor as lead. In this week's episodes, it will be revealed that RK will not start shoot for the movie even after the huge pooling in of money for the project. Even after repeated calls coming from Harshvardhan and his secretary Nikhil (Puneet Sachdev), RK will not report for shoot. This will actually be RK's game plan to teach Harshvardhan and his budding actor son a lesson that RK is supreme'. However, this will not go down well with Harshvardhan and he will come to RK's house and yell at him for the major monetary loss he would have been subjected to. An angry Harshvardhan will threaten to kill RK and his entire family by burning them to death.

Soon after this incident, the real action will take place.

RK's mansion will hold a festive atmosphere with the naming ceremony of his daughter to take place. Just before the ceremony, Bittooji's (Indresh Malik) wife Leela (Swati Anand) will get into labour, and will have to be rushed to the hospital. Thus Bittooji and his wife will be away from the RK mansion at the time of bomb blast.

RK and Madhu will be dancing away to glory when few goons dressed as waiters will enter the RK mansion and will place time bombs at various places in a discrete manner. Radha (Shama Deshpande) and the little kid will be together, as RK and Madhu will be busy romancing on the dance floor. This will be when the little kid will start crying. Radha in order to take her away from the hustle-bustle will come out of the mansion into the garden area. And this will be when the massive explosion will take place. RK and Madhu will be charred to death in the explosion.

Meanwhile, Radha will understand that her life as well as the little one's life is in danger. So she will flee from the place, without even getting to see a glimpse of her dead son and daughter-in-law.

If sources are to be believed, Radha will take the kid along with her to an unknown destination. Our source tells us that she will be forced to board a train which will leave her at Mathura.

Is it Harshvardhan or his secretary Nikhil behind the bomb blast? How will the journey of the little kid proceed from here?

We tried calling Shama but she remained unavailable for comments.

Get ready for an emotional outburst as you watch the episodes to come.
