I know the story line is ridiculous, but crazier things have been happening around us (if you follow news of how US finance guys that caused the financial collapse are getting bigger bonuses, and tax cuts, while common people like teachers are getting pay cuts, losing jobs, and are portrayed as parasites).
But, even in the relatively depressing reality, the DSDV storyline is going downhill, and I am sure after a few months, they will show Krushna making one mistake (like boasting about his plan when he thinks no one is hearing) and game over.
If any of you see "yahan main ghar ghar kheli", they closed one painful chapter of over four months in less than one episode. Bad guys plan and succeed everytime (they hear whenever some important thing is being planned), they can recover from horrible mistakes, everyone can hear others' phones but no one can record anything ever! After the silly trips, the bad guys make one big boast and are done in one episode! If only the villians can learn that they shouldn't publicly shout out their entire plan aloud, they will never get caught!
Oh, the villian woman shows up at the hospital as a doc too -- happened a few months ago, may be they are recycling portions of the scripts!
