yea, i agree they have chosen to push Satya's mysterious death under the rug! Infact i posted abt Satya's death not being solved, yesterday in another post.. this is what i said..
During the time when we were shown a mystery man following lax-satya, they always made it a point to show us a cat, house etc. And the day they first revealed Karan's true intentions of constantly pursuing Laxmi, they again showed us karan with the cat in the same house etc. Now what are the odds of the mystery man and Karan having the exact same tastes? And i don't think it was to set us off track. I think they just made a change in the script seeing how well the viewers have accepted Karan's character as Laxmi's new hero.
Maybe karan is not the killer. I think when the creatives started on the mystery man's track, they may have started off that way, that Karan will kill satya and will be the one to bring Laxmi's life back to normal, only later for her to find out that he was the one to shatter her life in the first place. And then when Karan's track began.. everyone noticed the awesome chemistry b/w Lax and Karan and the creatives must've thought that karan might make a good replacement for Satya in Laxmi's life and they completely ignored the evidences they kept showing us regarding Satya's death. I don't think they will ever disclose what happened that day on the cliff. I think Satya's death will remain as one of the unsolved mysteries in this show.
