vandana- kajali/ sheela

im sure vandana liked kajal and far more than sheela. correct me if something i have written is wrong but y would somone (vandana) blame sheela for kajal murder if she wanted sheela to become her dil and then think of getting sheela married to rohan. Vandana knows sheela dont love rohan while rohan thinks sheela loves her and rohan loves sheela. also if vandana wants to get a kid from sheela and then dump sheela that would be stpid as rohan loves sheela and he wouldnt dump her altho sheela would to get revenge
