Connection between Kaabil and Koi Mill Gaya

I think between kmg and kaabil there exists an unreleased film. a hater fiction story goes like,

Jadoo (alien) come down to earth again and while.returning back he take away eyesight he gave to Rohit. Rohit turns blind and then story moves forward in kaabil. This is all assumption. Don't you think we deserve a movie illustrating exactly how and why it happened the way it happened?? What went wrong between jadoo and Rohit??

Disgust please.
