Alokh behind shiv kidnaping - Page 2

I think what happend is alok was witness in some case and culprit got 7 yrs to prison because of his statement and now culprit came out of prison and to take revenge from alok he kidnapped shiv and may kill him or something but to get new shiv in the show they will show that shiv escaped and came back...

one thing i do not understand is why do you have to kill somebody or make them disappear you can just change the actor like i have seen in other indian soaps as well as in english soaps...
